| vacuolar ATPase | <enzyme> From eukaryotic endomembrane systems, including vacuoles, lysosomes, golgi apparatus, chromaffin granules and coated vesicles. One of three major classes of ion transport ATPase, characterised by a multi subunit structure and a lack of a phosphorylated intermediate. Found in archaebacteria but not eubacteria, in the intracellular acidic vacuoles and in some proton pumping epithelia (e.g. Intercalated cells of kidney). A complex enzyme encoded by several genes, involved in ion translocation but does not act via phosphorylated enzyme intermediate See: P-type ATPase. Registry number: EC 3.6.1.- Synonym: atpase, v-type, atpase, vacuolar, vacuolar atpase, v-atpase, vacuolar h+-atpase, vacuolar membrane h(+)-atpase, vha55 gene product, vma16 gene product (26 Jun 1999) |

| proton ATPase | <enzyme> An ion pump that actively transports hydrogen ions across lipid bilayers in exchange for ATP. Major groups are the F-type ATPases, that run in reverse to synthesise ATP in bacterial, mitochondrial and chloroplast membranes (ATP synthase) and the V-type ATPases found in intracellular vesicles with an acidic lumen and on certain epithelial cells (e.g. Kidney intercalated cells).
