Interpro abstract (IPR002379): | Transmembrane ATPases are membrane-bound enzyme complexes/ion transporters that use ATP hydrolysis to drive the transport of protons across a membrane. Some transmembrane ATPases also work in reverse, harnessing the energy from a proton gradient, using the flux of ions across the membrane via the ATPase proton channel to drive the synthesis of ATP. There are several different types of transmembrane ATPases, which can differ in function (ATP hydrolysis and/or synthesis), structure (e.g., F-, V- and A-ATPases, which contain rotary motors) and in the type of ions they transport [ (PUBMED:15473999) (PUBMED:15078220) ]. The different types include:
The F-ATPases (or F1F0-ATPases) and V-ATPases (or V1V0-ATPases) are each composed of two linked complexes: the F1 or V1 complex contains the catalytic core that synthesizes/hydrolyses ATP, and the F0 or V0 complex that forms the membrane-spanning pore. The F- and V-ATPases all contain rotary motors, one that drives proton translocation across the membrane and one that drives ATP synthesis/hydrolysis [ (PUBMED:11309608) (PUBMED:15629643) ]. In V-ATPases, there are three proteolipid subunits (c, c' and c'') that form part of the proton-conducting pore, each containing a buried glutamic acid residue that is essential for proton transport, and together they form a hexameric ring spanning the membrane [ (PUBMED:15951435) (PUBMED:14635779) ]. Structurally, the c subunits consist of a two antiparallel transmembrane helices. Both helices of one c subunit are connected by a loop on the cytoplasmic side [ (PUBMED:19783985) ]. This entry represents the V-ATPase proteolipid subunit C like domain found in the V-ATPase proteolipid subunit C and the F-ATP synthase subunit C. |
