General description
Phospholipase A2 is a small disulfide-rich protein having 124 residues. It is a calcium-dependent enzyme.
Application
Phospholipase A2 has been used in phospholipase assay and to determine rat renal proximal tubular segments (PTS) viability during oxygenation and hypoxia-reoxygenation.
Biochem/physiol Actions
It has a high catalytic activity on aggregated substrates compared to monomeric substrates.
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.
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 at 37 °C.
Physical form
Suspension in 3.2 M (NH4)2SO4 solution, pH 5.5
