Iso_dh Isocitrate/isopropylmalate dehydrogenase

SMART accession number:	SM01329
Description:	Isocitrate dehydrogenase (IDH), is an important enzyme of carbohydrate metabolism which catalyses the oxidative decarboxylation of isocitrate into alpha-ketoglutarate.
Interpro abstract (IPR024084):	This entry represents a structural domain found in all types of isocitrate dehydrogenase, and in isopropylmalate dehydrogenase and tartrate dehydrogenase. The crystal structure of Escherichia coli isopropylmalate dehydrogenase has been described [ (PUBMED:9086278) ]. The isocitrate and isopropylmalate dehydrogenases family includes isocitrate dehydrogenase (IDH), 3-isopropylmalate dehydrogenase (IMDH) and tartrate dehydrogenase. IDH is an important enzyme of carbohydrate metabolism which catalyses the oxidative decarboxylation of isocitrate into alpha-ketoglutarate [ (PUBMED:2682654) (PUBMED:1939242) ]. IDH is either dependent on NAD ⁺ ( EC 1.1.1.41 ) or on NADP ⁺ ( EC 1.1.1.42 ). In eukaryotes there are at least three isozymes of IDH: two are located in the mitochondrial matrix (one NAD ⁺ -dependent, the other NADP ⁺ -dependent), while the third one (also NADP ⁺ -dependent) is cytoplasmic. In Escherichia coli, the activity of a NADP ⁺ -dependent form of the enzyme is controlled by the phosphorylation of a serine residue; the phosphorylated form of IDH is completely inactivated. IMDH ( EC 1.1.1.85 ) catalyses the third step in the biosynthesis of leucine in bacteria and fungi, the oxidative decarboxylation of 3-isopropylmalate into 2-oxo-4-methylvalerate [ (PUBMED:1748999) (PUBMED:7773180) ]. Tartrate dehydrogenase ( EC 1.1.1.93 ) shows strong homology to prokaryotic isopropylmalate dehydrogenases and, to a lesser extent, isocitrate dehydrogenase [ (PUBMED:8053675) ]. It catalyses the reduction of tartrate to oxaloglycolate [ (PUBMED:8053675) ].

- Display abstract
- NAD(+)-dependent isocitrate dehydrogenase from Saccharomyces cerevisiae iscomposed of two nonidentical subunits, designated IDH1 (Mr approximately 40,000) and IDH2 (Mr approximately 39,000). We have isolated and characterized a yeastgenomic clone containing the IDH2 gene. The amino acid sequence deduced from the gene indicates that IDH2 is synthesized as a precursor of 369 amino acids (Mr39,694) and is processed upon mitochondrial import to yield a mature protein of354 amino acids (Mr 37,755). Amino acid sequence comparison between S. cerevisiaeIDH2 and S. cerevisiae NADP(+)-dependent isocitrate dehydrogenase shows nosignificant sequence identity, whereas comparison of IDH2 and Escherichia coliNADP(+)-dependent isocitrate dehydrogenase reveals a 33% sequence identity. Toconfirm the identity of the IDH2 gene and examine the relationship between IDH1and IDH2, the IDH2 gene was disrupted by genomic replacement in a haploid yeaststrain. The disruption strain expressed no detectable IDH2, as determined byWestern blot analysis, and was found to lack NAD(+)-dependent isocitratedehydrogenase activity, indicating that IDH2 is essential for a functionalenzyme. Overexpression of IDH2, however, did not result in increasedNAD(+)-dependent isocitrate dehydrogenase activity, suggesting that both IDH1 andIDH2 subunits are required for catalytic activity. The disruption strain wasunable to utilize acetate as a carbon source and exhibited a 2-fold slower growthrate than wild type strains on glycerol or lactate. This growth phenotype isconsistent with NAD(+)-dependent isocitrate dehydrogenase performing an essentialrole in the oxidative function of the citric acid cycle.

- Display abstract
- The structure of isocitrate dehydrogenase [threo-DS-isocitrate: NADP+oxidoreductase (decarboxylating), EC 1.1.1.42] from Escherichia coli has beensolved and refined at 2.5 A resolution and is topologically different from thatof any other dehydrogenase. This enzyme, a dimer of identical 416-residuesubunits, is inactivated by phosphorylation at Ser-113, which lies at the edge ofan interdomain pocket that also contains many residues conserved betweenisocitrate dehydrogenase and isopropylmalate dehydrogenase. Isocitratedehydrogenase contains an unusual clasp-like domain in which both polypeptidechains in the dimer interlock. Based on the structure of isocitrate dehydrogenaseand conservation with isopropylmalate dehydrogenase, we suggest that the activesite lies in an interdomain pocket close to the phosphorylation site.
