A subcategory of secreted phospholipases a2 with specificity for phosphatidylethanolamines and PHOSPHATIDYLCHOLINE. It occurs as a component of venoms and as a mammalian secretory phospholipase A2. The creation of this group is based upon similarities in the structural determinants of the enzymes including a long amino-terminal domain, a conserved group III-specific domain, and a long carboxyl-terminal domain.
