In vivo, induces edema and produces neurotoxic symptoms in mice. Also exhibits indirect hemolysis, a strong myonecrotic activity and cytotoxicity. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Monomer: Snake venom phospholipase A2 (PLA2) that shows a PLA2 activity of 578 umol/min/mg. | ||
