EFhEF-hand, calcium binding motif
|SMART accession number:||SM00054|
|Description:||EF-hands are calcium-binding motifs that occur at least in pairs. Links between disease states and genes encoding EF-hands, particularly the S100 subclass, are emerging. Each motif consists of a 12 residue loop flanked on either side by a 12 residue alpha-helix. EF-hands undergo a conformational change unpon binding calcium ions.|
|Interpro abstract (IPR002048):||Many calcium-binding proteins belong to the same evolutionary family and share a type of calcium-binding domain known as the EF-hand. This type of domain consists of a twelve residue loop flanked on both sides by a twelve residue alpha-helical domain. In an EF-hand loop the calcium ion is coordinated in a pentagonal bipyramidal configuration. The six residues involved in the binding are in positions 1, 3, 5, 7, 9 and 12; these residues are denoted by X, Y, Z, -Y, -X and -Z. The invariant Glu or Asp at position 12 provides two oxygens for liganding Ca (bidentate ligand).|

EF-hand proteins undergo conformational changes upon binding of Ca2+. This event is a crucial step in many Ca2+-dependent cellular processes. Recent advances in the three-dimensional structural analysis of various EF-hand proteins have led to new insights into the structure and functional relationship of this large family of Ca2+-binding proteins.

Calcium lons as second messengers control many biological processes, at least in part, via interaction with a large number of Ca(2+)-binding proteins. One class of these proteins shares a common Ca(2+)-binding motif, the EF-hand, Here, we describe some functional aspects of EF-hand proteins, which have been found recently in different cellular compartments. Novel links between EF-hand proteins, particularly S100 proteins, and specific diseases are now emerging.

- Solution structure of (Cd2+)1-calbindin D9k reveals details of the stepwise structural changes along the Apo-->(Ca2+)II1-->(Ca2+)I,II2 binding pathway.
- J Mol Biol. 1995; 252: 102-21
- Display abstract
The three-dimensional solution structure of (Cd2+)1-calbindin D9k has been determined by distance geometry, restrained molecular dynamics and relaxation matrix calculations using experimental constraints obtained from two-dimensional 1H and 15N-1H NMR spectroscopy. The final input data consisted of 1055 NOE distance constraints and 71 dihedral angle constraints, corresponding to 15 constraints per residue on average. The resulting ensemble of 24 structures has no distance or dihedral angle constraints consistently violated by more than 0.07 A and 1.8 degrees, respectively. The structure is characteristic of an EF-hand protein, with two helix-loop-helix calcium binding motifs joined by a flexible linker, and a short anti-parallel beta-type interaction between the two ion-binding sites. The four helices are well defined with a root mean square deviation from the mean coordinates of 0.35 A for the backbone atoms. The structure of the half-saturated cadmium state was compared with the previously determined solution structures of the apo and fully calcium saturated calbindin D9k. The comparisons were aided by introducing the ensemble averaged distance difference matrix as a tool for analyzing differences between two ensembles of structures. Detailed analyses of differences between the three states in backbone and side-chain dihedral angles, hydrogen bonds, interatomic distances, and packing of the hydrophobic core reveal the reorganization of the protein that occurs upon ion binding. Overall, it was found that (Cd2+)1-calbindin D9k, representing the half-saturated calcium state with an ion in site II, is structurally more similar to the fully calcium-saturated state than the apo state. Thus, for the binding sequence apo-->(Ca2+)II1-->(Ca2+)I,II2, the structural changes occurring upon ion binding are most pronounced for the first binding step, an observation that bears significantly on the molecular basis for cooperative calcium binding in calbindin D9k.

- Nat Struct Biol. 1995; 2: 790-6
- Display abstract
The S100 calcium-binding proteins are implicated as effectors in calcium-mediated signal transduction pathways. The three-dimensional structure of the S100 protein calcyclin has been determined in solution in the apo state by NMR spectroscopy and a computational strategy that incorporates a systematic docking protocol. This structure reveals a symmetric homodimeric fold that is unique among calcium-binding proteins. Dimerization is mediated by hydrophobic contacts from several highly conserved residues, which suggests that the dimer fold identified for calcyclin will serve as a structural paradigm for the S100 subfamily of calcium-binding proteins.

- Display abstract
The three-dimensional structure of apo calbindin D9k has been determined using constraints generated from nuclear magnetic resonance spectroscopy. The family of solution structures was calculated using a combination of distance geometry, restrained molecular dynamics, and hybrid relaxation matrix analysis of the nuclear Overhauser effect (NOE) cross-peak intensities. Errors and inconsistencies in the input constraints were identified using complete relaxation matrix analyses based on the results of preliminary structure calculations. The final input data consisted of 994 NOE distance constraints and 122 dihedral constraints, aided by the stereospecific assignment of the resonances from 21 beta-methylene groups and seven isopropyl groups of leucine and valine residues. The resulting family of 33 structures contain no violation of the distance constraints greater than 0.17 A or of the dihedral angle constraints greater than 10 degrees. The structures consist of a well-defined, antiparallel four-helix bundle, with a short anti-parallel beta-interaction between the two unoccupied calcium-binding loops. The root-mean-square deviation from the mean structure of the backbone heavy-atoms for the well-defined helical residues is 0.55 A. The remainder of the ion-binding loops, the linker loop connecting the two sub-domains of the protein, and the N and C termini exhibit considerable disorder between different structures in the ensemble. A comparison with the structure of the (Ca2+)2 state indicates that the largest changes associated with ion-binding occur in the middle of helix IV and in the packing of helix III onto the remainder of the protein. The change in conformation of these helices is associated with a subtle reorganization of many residues in the hydrophobic core, including some side-chains that are up to 15 A from the ion-binding site.

- Calcium-induced dimerization of troponin C: mode of interaction and use of trifluoroethanol as a denaturant of quaternary structure.
- Biochemistry. 1995; 34: 7365-75
- Display abstract
Protein aggregation can be a problem, especially as a large number of proteins become available for structural studies at fairly high concentrations using solution techniques such as NMR spectroscopy. The muscle regulatory protein troponin C (TnC) undergoes a calcium-induced dimerization at neutral pH with a dissociation constant for the dimerization of 0.4 mM at 20 degrees C. The present study indicates that the mode of dimerization involves the N-domain of one monomer interacting with the N-domain of another monomer. Addition of the solvent trifluoroethanol (TFE) to a concentration of 15%, v/v, results in a 10-fold increase in the dimer dissociation constant of calcium-saturated TnC (4 mM at 20 degrees C), making TnC predominantly a monomer for spectroscopic studies. Further, TFE, at the concentrations used herein, acts to perturb the quaternary structure of TnC without adversely affecting the secondary or tertiary structure as evidenced by minimal changes to its CD spectra and 1H, 13C, and 15N NMR chemical shifts.

- Display abstract
The solution secondary structure of calcium-saturated skeletal troponin C (TnC) in the presence of 15% (v/v) trifluoroethanol (TFE), which has been shown to exist predominantly as a monomer (Slupsky CM, Kay CM, Reinach FC, Smillie LB, Sykes BD, 1995, Biochemistry 34, forthcoming), has been investigated using multidimensional heteronuclear nuclear magnetic resonance spectroscopy. The 1H, 15N, and 13C NMR chemical shift values for TnC in the presence of TFE are very similar to values obtained for calcium-saturated NTnC (residues 1-90 of skeletal TnC), calmodulin, and synthetic peptide homodimers. Moreover, the secondary structure elements of TnC are virtually identical to those obtained for calcium-saturated NTnC, calmodulin, and the synthetic peptide homodimers, suggesting that 15% (v/v) TFE minimally perturbs the secondary and tertiary structure of this stably folded protein. Comparison of the solution structure of calcium-saturated TnC with the X-ray crystal structure of half-saturated TnC reveals differences in the phi/psi angles of residue Glu 41 and in the linker between the two domains. Glu 41 has irregular phi/psi angles in the crystal structure, producing a kink in the B helix, whereas in calcium-saturated TnC, Glu 41 has helical phi/psi angles, resulting in a straight B helix. The linker between the N and C domains of calcium-saturated TnC is flexible in the solution structure.

The backbone resonance assignments have been completed for the apo (1H and 15N) and calcium-loaded (1H, 15N, and 13C) regulatory N-domain of chicken skeletal troponin-C (1-90), using multidimensional homonuclear and heteronuclear NMR spectroscopy. The chemical-shift information, along with detailed NOE analysis and 3JHNH alpha coupling constants, permitted the determination and quantification of the Ca(2+)-induced secondary structural change in the N-domain of TnC. For both structures, 5 helices and 2 short beta-strands were found, as was observed in the apo N-domain of the crystal structure of whole TnC (Herzberg O, James MNG, 1988, J Mol Biol 203:761-779). The NMR solution structure of the apo form is indistinguishable from the crystal structure, whereas some structural differences are evident when comparing the 2Ca2+ state solution structure with the apo one. The major conformational change observed is the straightening of helix-B upon Ca2+ binding. The possible importance and role of this conformational change is explored. Previous CD studies on the regulatory domain of TnC showed a significant Ca(2+)-induced increase in negative ellipticity, suggesting a significant increase in helical content upon Ca2+ binding. The present study shows that there is virtually no change in alpha-helical content associated with the transition from apo to the 2Ca2+ state of the N-domain of TnC. Therefore, the Ca(2+)-induced increase in ellipticity observed by CD does not relate to a change in helical content, but more likely to changes in spatial orientation of helices.

The three-dimensional structure of calbindin D9k in the absence of Ca2+ has been determined using NMR spectroscopy in solution, allowing the first direct analysis of the consequences of Ca2+ binding for a member of the calmodulin superfamily of proteins. The overall response in calbindin D9k is much attenuated relative to the current model for calmodulin and troponin C. These results demonstrate a novel mechanism for modulating the conformational response to Ca(2+)-binding in calmodulin superfamily proteins and provide insights into how their Ca(2+)-binding domains can be fine-tuned to remain essentially intact or respond strongly to ion binding, in relation to their functional requirements.

- Display abstract
The three-dimensional solution structure of calcium-loaded calbindin D9k has been determined using experimental constraints obtained from nuclear magnetic resonance spectroscopy. A total of 1176 constraints (16 per residue overall, 32 per residue for the core residues) was used for the final refinement, including 1002 distance and 174 dihedral angle constraints. In addition, 23 hydrogen bond constraints were used for the generation of initial structures. Stereospecific assignments were made for 37 of 61 (61%) prochiral methylene protons and the methyl groups of all three valine residues and five out of 12 leucine residues. These constraints were used as input for a series of calculations of three-dimensional structures using a combination of distance geometry and restrained molecular dynamics. The 33 best structures selected for further analysis have no distance constraint violations greater than 0.3 A and good local geometries as reflected by low total energies (< or = -1014 kcal/mol in the AMBER 4.0 force field). The core of the protein consists of four well-defined helices with root-mean-square deviations from the average of 0.45 A for the N, C alpha and C' backbone atoms. These helices are packed in an antiparallel fashion to form two helix-loop-helix calcium-binding motifs, termed EF-hands. The two EF-hands are joined at one end by a ten-residue linker segment, and at the other by a short beta-type interaction between the two calcium-binding loops. Overall, the average solution structure of calbindin D9k is very similar to the crystal structure, with a pairwise root-mean-square deviation of 0.85 A for the N, C alpha and C' backbone atoms of the four helices. The differences that are observed between the solution and the crystal structures are attributed to specific crystal contacts, increased side-chain flexibility in solution, or artifacts arising from molecular dynamics refinement of the solution structures in vacuo.

- Display abstract
Results of studies of the Ca2+-dependent protein modulator of 3':5'-cyclic nucleotide phosphodiesterase isolated from bovine brain are presented which show its structural similarity to the Ca2+-binding subunit of muscle troponin. Both proteins have blocked NH2 termini, similar and characteristic ultraviolet absorption spectra, similar Ca2+-binding properties, very similar amino acid compositions, and co-migrate on sodium dodecyl sulfate-polyacrylamide gels. The primary structures of selected tryptic peptides isolated from bovine brain modulator protein are similar or identical with regions of the primary sequences of rabbit skeletal muscle and bovine cardiac muscle troponin C. Bovine brain modulator protein contains and unidentified ninhydrin-positive basic compound not found in muscle troponin C. An improved procedure is presented which yields 40 to 70 mg of modulator protein per kg of bovine brain.
