| membrane-bound proton-translocating PPi synthase | <enzyme> From rhodospirillum rubrum; functions as an alternative coupling factor; n,n'-dicyclohexylcarbodiimide-sensitive; catalyses the phosphorylation of pi to ppi, the hydrolysis of ppi and the concomitant translocation of proton across the plasma membrane Registry number: EC 3.6.1.- Synonym: h(+)-ppi synthase (26 Jun 1999) |
|---|---|
| ATP synthase | <enzyme> An enzyme that catalyses the conversion of phosphate and ADP into ATP during oxidativephosphorylation in mitochondriaand bacteria or photophosphorylationin chloroplasts. (09 Oct 1997) |
| hydrogen-transporting ATP synthase | <enzyme> A group of enzymes which are involved in the reversible synthesis of ATP and that transport protons from the cytoplasmic to the matrix side of the mitochondrial membrane. The flow of protons through the f(0) channel results in ATP synthesis by f1. Chemical name: ATP phosphohydrolase (H+-transporting) Registry number: EC 3.6.1.34 (12 Dec 1998) |
| cadmium translocating ATPase | <enzyme> Cadmium-efflux atpase; e1,e2-translocating atpase is a generic name which includes all cation-transport atpases; do not confuse with lysine decarboxylase cada Registry number: EC 3.6.1.- Synonym: cada atpase, cd-e1,e2-translocating atpase (26 Jun 1999) |
| sodium-translocating NADH-quinone reductase | <enzyme> From vibrio alginolyticus; na+ dependent activation is located in the NADH-quinone reductase segment; reduces ubiquinone-1 to ubisemiquinones or ubiquinol; strongly inhibited by 2-n-heptyl-4-hydroxyquinoline n-oxide; do not confuse with sodium independent NADH-quinone reductase EC 1.6.99.2 Registry number: EC 1.6.5.- Synonym: nqr-1, na-translocating NADH-quinone reductase, nqr gene product (26 Jun 1999) |
| K+-translocating Kdp-ATPase | <enzyme> An inducible high affinity k+ transporter in E coli Registry number: EC 3.6.1.- Synonym: potassium kdp atpase, kdp-atpase, kdpb protein (26 Jun 1999) |
| proton | <physics> An elementary atomic particle with a positive charge and a mass of about 1 amu. (09 Oct 1997) |
| proton acceptor | <chemistry> A base, an anionic substance that acceptsa proton during an acid-basereaction. (09 Oct 1997) |
| 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) |
| proton donor | <chemistry> An acid, a susbstance that donates protons in an acid-base reduction reaction. (10 Jan 1998) |
| proton-motive force | Energy that is generated by the transfer of protons or electrons across an energy-transducing membrane and that can be used for chemical, osmotic, or mechanical work. Proton-motive force can be generated by a variety of phenomena including the operation of an electron transport chain, illumination of a purple membrane, and the hydrolysis of ATP by a proton atpase. (12 Dec 1998) |
| proton pump | Integral membrane proteins that transport protons across a membrane against a concentration gradient. This transport is driven by hydrolysis of ATP by hydrogen-transporting ATP synthase. (12 Dec 1998) |
| proton pump inhibitor | <pharmacology> A group of anti-ulcer medications which work by binding to H+/K+ ATPase, an enzyme which is found on the secretory surface of parietal cells. It thereby inhibits the final transport of hydrogen ions (via exchange with potasium) into the gastric lumen. Examples of proton pump inhibitors include omeprazole and lansoprazole. (27 Sep 1997) |
| ATP | <biochemistry> A nucleotide present in all living cells which serves as an energy source for many metabolic processes and is required for ribonucleic acid synthesis. (06 May 1997) |
| ATP citrate lyase | ATP citrate (pro-3S)-lyase |
