This family consists of Lysophospholipase / phospholipase B EC:3.1.1.5 and cytosolic phospholipase A2 EC:3.1.4 which also has a C2 domain Pfam:PF00168. Phospholipase B enzymes catalyse the release of fatty acids from lysophsopholipids and are capable in vitro of hydrolysing all phospholipids extractable form yeast cells [1]. Cytosolic phospholipase A2 associates with natural membranes in response to physiological increases in Ca2+ and selectively hydrolyses arachidonyl phospholipids [2], the aligned region corresponds the the carboxy-terminal Ca2+-independent catalytic domain of the protein as discussed in [2].

Cytosolic phospholipases A2 (cPLA2s) consist of a family of calcium-sensitive enzymes that function to generate lipid second messengers through hydrolysis of membrane-associated glycerophospholipids. In humans, the cPLA2 family contains six isoforms. Structural information of full length cPLA2alpha apo form, shows that it is composed of two domains; an N-terminal Ca2 + binding C2 domain and a C-terminal alpha/beta hydrolase core. This entry describes the N-terminal Ca2+ binding C2 domain which is composed of an eight-stranded antiparallel beta-sandwich consisting of two four-stranded beta-sheets. C2 domains are present in many lipid-binding proteins including Copines, CAPRI and Rabphilin-3A all of which are involved in membrane trafficking [1].	Domain
