The enzyme lysophospholipase (EC 3.1.1.5) catalyzes the reaction

Contents

2-lysophosphatidylcholine + H2O glycerophosphocholine + a carboxylate

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. This family consists of lysophospholipase / phospholipase B (EC 3.1.1.5) and cytosolic phospholipase A2 which also has a C2 domain InterPro :  IPR000008 . Phospholipase B enzymes catalyse the release of fatty acids from lysophospholipids and are capable in vitro of hydrolyzing all phospholipids extractable from yeast cells. [1] Cytosolic phospholipase A2 associates with natural membranes in response to physiological increases in Ca2+ and selectively hydrolyses arachidonyl phospholipids, [2] the aligned region corresponds the carboxy-terminal Ca2+-independent catalytic domain of the protein as discussed in. [2]

The systematic name of this enzyme class is 2-lysophosphatidylcholine acylhydrolase. Other names in common use include lecithinase B, lysolecithinase, phospholipase B, lysophosphatidase, lecitholipase, phosphatidase B, lysophosphatidylcholine hydrolase, lysophospholipase A1, lysophopholipase L2, lysophospholipase transacylase, neuropathy target esterase, NTE, NTE-LysoPLA, and NTE-lysophospholipase. This enzyme participates in glycerophospholipid metabolism.

Micrococcal nuclease is an endo-exonuclease that preferentially digests single-stranded nucleic acids. The rate of cleavage is 30 times greater at the 5' side of A or T than at G or C and results in the production of mononucleotides and oligonucleotides with terminal 3'-phosphates. The enzyme is also active against double-stranded DNA and RNA and all sequences will be ultimately cleaved.

<span class="mw-page-title-main">1-Lysophosphatidylcholine</span>

1-Lysophosphatidylcholines are a class of phospholipids that are intermediates in the metabolism of lipids. They result from the hydrolysis of an acyl group from the sn-1 position of phosphatidylcholine. They are also called 2-acyl-sn-glycero-3-phosphocholines. The synthesis of phosphatidylcholines with specific fatty acids occurs through the synthesis of 1-lysoPC. The formation of various other lipids generates 1-lysoPC as a by-product.
