| oxidative phosphorylation | <biochemistry> The phosphorylation of ATP coupled to the respiratory chain. (18 Nov 1997) |

| magnesium protoporphyrin monomethyl ester oxidative cyclase | <enzyme> In chlorophyll biosynthesis converts -(ch2)2-coo-ch3 side chain of mg protoporphyrin monomethyl ester to -c=o-ch-cooch3 ring of mg 2,4-divinyl phaeoporphyrin a(5) monomethyl ester; requires NADPH and molecular oxygen; similar to cytochrome p-450 catalyzed systems but not inhibited by co Registry number: EC 1.14.13.- Synonym: mpme-oxidative cyclase (26 Jun 1999) |
|---|---|
| phosphorylation | <biochemistry> The creation of a phosphate derivative of an organic molecule. This isusually achieved by transferring a phosphate group from ATP. (09 Oct 1997) |
| phosphorylation of proteins | <biochemistry> Addition of phosphate groups to hydroxyl groups on proteins (side chains s, T or Y) catalysed by a protein kinase often specific) with ATP as phosphate donor. Activity of proteins is often regulated by phosphorylation. (18 Nov 1997) |
| mitochondrial oxidative damage endonuclease | <enzyme> An 8-oxog-specific DNA endonuclease from rat liver mitochondria; recognises and incises at 8-oxog and abasic acid sites in duplex DNA Registry number: EC 3.1.25.- Synonym: oxidative damage-specific endonuclease, mtode enzyme (26 Jun 1999) |
| cyclic phosphorylation | Any process in which a phosphatide ester forms a cylic diester by linkage to a neighbouring hydroxyl group. (18 Nov 1997) |
| substrate-level phosphorylation | Synthesis of high-energy phosphate bonds through reaction of inorganic phosphate with an activated (usually) organic substrate. (09 Oct 1997) |
| oxidative | Having the power to oxidise; denoting a process involving oxidation. (05 Mar 2000) |
| oxidative metabolism | Respiration in the biochemical sense. (18 Nov 1997) |
| oxidative stress | A highly oxidized environment within cells that is thought to promote HIV replication because cells are forced into a highly activated state due to loss of control of their regulatory systems. (09 Oct 1997) |
| electron transport phosphorylation | <biochemistry> Synthesis of ATP involving a membrane associated electron transport chain and the creation of a proton-motive force. (09 Oct 1997) |
| tyrosine phosphorylation | <enzyme> Kinases that phosphorylate protein tyrosine residues. These kinases play major roles in mitogenic signalling and can be divided into two subfamilies: receptor tyrosine kinases, that have an extracellular ligand binding domain, a single transmembrane domain and an intracellular tyrosine kinase domain and nonreceptor tyrosine kinases, which are soluble, cytoplasmic kinases. (18 Nov 1997) |
| lactic acid oxidative decarboxylase | A flavoprotein oxidoreductase catalyzing oxidation (with O2) of l-lactate to acetate plus CO2 and water. Synonym: lactic acid oxidative decarboxylase. (05 Mar 2000) |
