| 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. Chemical name: ATP phosphohydrolase (H+/K+-transporting) Registry number: EC 3.6.1.36 (12 Dec 1998) |
| single stranded DNA dependent ATPase | <enzyme> Probably involved in DNA replication Registry number: EC 3.6.1.- Synonym: ssdna-dependent atpase (26 Jun 1999) |
| sodium ammonium ATPase | <enzyme> Aspect of atpase, EC 3.6.1.3 Registry number: EC 3.6.1.- Synonym: ammonium potassium atpase, na nh4 atpase, atpase, sodium ammonium (26 Jun 1999) |
| sodium ATPase | <enzyme> Na activated, mg dependent atpase; aspect of atpase, EC 3.6.1.3 Registry number: EC 3.6.1.- Synonym: sodium adenosine triphosphatase, na atpase, atpase, sodium, sodium-translocating atpase (26 Jun 1999) |
| sodium potassium ATPase | <enzyme> A major transport protein of the plasma membrane. A multi unit enzyme, it moves 3 sodium ions out of the cell and 2 potassium ions in, for each ATP hydrolysed. The sodium gradient established is used for several purposes (see facilitated diffusion, action potential), while the potassium gradient is dissipated through the potassium leak channel. Must not be confused with a sodium channel. (18 Nov 1997) |
| sodium-potassium-exchanging atpase | <enzyme> An enzyme that catalyses the active transport system of sodium and potassium ions across the cell wall. Sodium and potassium ions are closely coupled with membrane atpase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients. Chemical name: ATP phosphohydrolase (sodium-potassium-transporting) Registry number: EC 3.6.1.37 (12 Dec 1998) |
| DNA-dependent ATPase | <enzyme> Factor y is a phage 174 specific DNA-dependent atpase; atpase I can act with double-stranded DNA; atpase II and III require single-stranded DNA; a18r from vaccinia virus Registry number: EC 3.6.1.- Synonym: DNA helicase II, factor y, DNA-dependent atpase I, DNA-dependent atpase II, DNA-dependent atpase III, rep protein (E coli), atpase, DNA-dependent, DNA-dependent atpase iv, uvrd protein, rep helicase, pri a protein, protein n', rip100, pria helicase, pria protein (helicase), a18r gene product, DNA helicase a (26 Jun 1999) |
| DNA-dependent ATPase-endonuclease | <enzyme> Atpase and endonuclease are part of a single protein from phage t4 infected E coli; atpase is activated by duplex, single-stranded or supercoiled DNA Registry number: EC 3.1.21.- Synonym: atpase-endonuclease (26 Jun 1999) |
| dynein atpase | <enzyme> A structural protein which forms the arms on the microtubule doublets of cilia and flagella. In the presence of divalent cations, dynein catalyses the hydrolysis of ATP. This hydrolysis plays an important functional role in the motility process. Chemical name: Dynein ATP phosphohydrolase (tubulin-translocating) Registry number: EC 3.6.1.33 (12 Dec 1998) |
| TER ATPase | <enzyme> Catalyses hydrolysis of (gamma(32)-p)ATP and is phosphorylated in presence of magnesium(ii); hexamer of 100-kD subunits; isolated from transitional endoplasmic reticulum; genbank u11760 Registry number: EC 3.6.1.- (26 Jun 1999) |
| E1E2 ATPase | <enzyme> An enzyme that hydrolyzes ATP into ADP and phosphate. (09 Oct 1997) |
