描述
| 应用 | Phospholipase A2 has been used in phospholipase assay and to determine rat renal proximal tubular segments (PTS) viability during oxygenation and hypoxia-reoxygenation. |
| 产品介绍 | Phospholipase A2 is a member of the class of heat-stable, calcium-dependent enzymes catalyzing the hydrolysis of the 2-acyl bond of 3-n-phosphoglycerides. The enzyme has a molecular weight of 30,000 daltons. Phospholipase A2 is activated by Ca2+. It is inhibited by zinc, barium, and manganese ions. Activity values for phospholipase A preparations which are derived from titrimetric assay procedures can be quite dependent on source and type of lecithin, its preparation as a substrate emulsion, other components of the reaction mixture, and the method and instrumentation used. |
| 备注 | A chromatographically purified, dialyzed, lyophilized powder. |
| 生化机理 | Hydrolyzes the β-ester bond of zwitterionic glycerophospholipids. Preferred substrates are phosphatidylcholine, phosphatidylethanolamine, and their plasmalogen analogues. Phosphatidylinositol and phosphatidylserine are also hydrolyzed. Aggressively attacks phospholipids in membranes of intact cells. It has a high catalytic activity on aggregated substrates compared to monomeric substrates. |
| 别名 | ;PLA2;Lecithinase A;Phosphatidylcholine 2-acylhydrolase |
