| V-type 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) |

| CopA ATPase | <enzyme> A p-type cation-transporting atpase involved in copper homeostasis in enterococcus hirae; exhibits sequence similarity to copb (atpase) and human mc1 protein; 727 amino acids, mw 87 kD Registry number: EC 3.6.1.- (26 Jun 1999) |
| CopB ATPase | <enzyme> A p-type cation-transporting atpase involved in copper homeostasis in enterococcus hirae; exhibits sequence similarity to copa (atpase) and human mc1 protein; 745 amino acids, mw 93 kD Registry number: EC 3.6.1.- (26 Jun 1999) |
| myosin atpase | <enzyme> An enzyme that catalyses the hydrolysis of myosin ATP in the presence of actin to form myosin ADP and orthophosphate. This reaction is the immediate source of free energy that drives muscle contraction. In the absence of actin, myosin atpase activity is low and requires calcium ions. Chemical name: Myosin ATP phosphohydrolase (actin-translocating) Registry number: EC 3.6.1.32 (12 Dec 1998) |
| 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). Gastric H/K ATPase is a proton ATPase. (18 Nov 1997) |
| S-(dinitrophenyl)glutathione ATPase | <enzyme> Anionic conjugates of bilirubin and bile acids stimulate the hydrolysis of the above enzyme of human erythrocyte; also found in other tissue Registry number: EC 3.6.1.- Synonym: dnp-sg-atpase (26 Jun 1999) |
| P-type ATPase | <enzyme> One of three major classes of ion transport ATPases, characterised by vanadate sensitivity and a phosphorylated intermediate. The archetype is the sodium pump. See: F-type ATPase, V-type ATPase. (18 Nov 1997) |
| hydrogen-potassium-exchanging atpase | <enzyme> An enzyme isolated from the gastric mucosa that catalyses the hydrolysis of ATP coupled with the exchange of hydrogen and potassium ions across the cell wall.
