| phospholipase | <enzyme> That hydrolyse ester bonds in phospholipids. They comprise two types: aliphatic esterases (phospholipase A1, A2 and B) that release fatty acids and phosphodiesterases (types C and D) that release diacyl glycerol or phosphatidic acid respectively. Type A2 is widely distributed in venoms and digestive secretions. Types A1, A2 and C the latter specific for phosphatidyl inositol) are present in all mammalian tissues. Type C is also found as a highly toxic secretion product of pathogenic bacteria. Type B attacks monoacyl phospholipids and is poorly characterised. Type D is largely of plant origin. PLA2 Type II (a secreted enzyme, but not the same as the Type I digestive pancreatic enzyme) is probably very important in inflammation because its action can release arachidonic acid, the starting point for eicosanoid synthesis. Phosphatidyl inositol bisphosphate specific phospholipase C is important in generating diacyl glycerol and inositol trisphosphate, both second messengers. (31 Dec 1997) |
|---|---|
| phospholipase A1 | <enzyme> An enzyme that hydrolyzes a lecithin (1,2-diacylglycerophosphocholine) to a 2-acylglycerophosphocholine and a fatty acid anion. (05 Mar 2000) |
| phospholipase A2 | <enzyme> An enzyme that catalyses the hydrolysis of a lecithin to a lysolecithin by removing the 2-acyl group; also acts on other phospholipids by removing a fatty acid from the 2-position; this enzyme has an important role in prostaglandin and leukotriene biosynthesis. Synonym: lecithinase A, phosphatidase, phosphatidolipase. (05 Mar 2000) |
| phospholipase B | There are reports that phospholipase B is a mixture of phospholipase A1 and phospholipase A2. See: lysophospholipase. (05 Mar 2000) |
| phospholipase c | <enzyme> An enzyme found in the alpha-toxin of clostridium welchii and other strains of clostridia and bacilli. It hydrolyzes glycerophosphatidates with the formation of 1,2-diacylglycerol and a phosphorylated nitrogenous base such as choline. Chemical name: Phosphatidylcholine cholinephosphohydrolase Registry number: EC 3.1.4.3 (12 Dec 1998) |
| phospholipase d | <enzyme> An enzyme found mostly in plant tissue. It hydrolyzes glycerophosphatidates with the formation of a phosphatidic acid and a nitrogenous base such as choline. This enzyme also catalyses transphosphatidylation reactions. Chemical name: Phosphatidylcholine phosphatidohydrolase Registry number: EC 3.1.4.4 (12 Dec 1998) |
| phospholipases | <enzyme> A class of enzymes that catalyze the hydrolysis of phosphoglycerides or glycerophosphatidates. Registry number: EC 3.1.- (12 Dec 1998) |
| phospholipases a | <enzyme> Phosphatide acylhydrolases. Catalyze the hydrolysis of one of the acyl groups of phosphoglycerides or glycerophosphatidates. Phospholipase a1 hydrolyzes the acyl group attached to the 1-position (ec 3.1.1.32) and phospholipase a2 hydrolyzes the acyl group attached to the 2-position (ec 3.1.1.4). Registry number: EC 3.1.1.- (12 Dec 1998) |

| phospholipase |
any of a number of enzymes that catalyze the hydrolysis of specific ester bonds in phospholipids. Individual enzymes are grouped on the basis of the bond they hydrolyze and are further categorized as carboxylic acid esterases (p. A1, p. A2) or phosphodiesterases (p. C, p. D).
