生化/生理作用

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.

其他说明

The toxic phospholipase A2 from Naja mossambica mossambica.

单位定义

One unit will hydrolyze 1.0 μmole of soybean L-α-phosphatidylcholine to L-α-lysophosphatidylcholine and a fatty acid per min at pH 8.9 at 25 °C.
