| lecithinase 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) |

| lecithinase | <enzyme> See phospholipases. (18 Nov 1997) |
|---|---|
| lecithinase A | <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) |
| lecithinase B | <enzyme> An enzyme that catalyses the hydrolysis of a single fatty acid ester bond in lysoglycerophosphatidates with the formation of glyceryl phosphatidates and a fatty acid. Chemical name: 2-Lysophosphatidylcholine acylhydrolase Registry number: EC 3.1.1.5 (12 Dec 1998) |
| lecithinase 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) |
