Snake venom phospholipase A2 homolog that induces myonecrosis, and edema. Has low myotoxic activity. Homodimer. Expressed by the venom gland. LD(50) is in the range of 6.25-12.5 mg/kg by intraperitoneal injection into mice. Belongs to the phospholipase A2 family. Group II subfamily. R49 sub-subfamily.
