l Biological Information

Biochem/Physiol Actions

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.

Application

Phospholipase A² from bovine pancreas has been used to determine rat renal proximal tubular segments (PTS) viability during oxygenation and hypoxia-reoxygenation and to study the impact of phospholipase A² on tubular cell triglyceride levels.

Preparation Note

This product is soluble in water (1 mg/ml), yielding a clear, colorless solution.

Unit Definition

One unit will hydrolyze 1.0 μmole of soybean L-α-phosphatidylcholine to L-α-lysophosphatidylcholine and a fatty acid per min at pH 8.0 and 37 °C.
