STRUCTURE OF CYTOSOLIC PHOSPHOLIPASE:Cytosolic phospholipase A2s has molecular weight, 85 kDa belong to group VI.Unlike the majority of PLA2s with the catalytic histidine,these enzymes have serine residue in the active site.Intracellular phospholipases are calcium- sensitive enzymes. They are large ( 700 a.a.)molecules containing specific C2 domain responsible for the protein transport to the plasma membrane.

The venom of the Eastern diamondback rattler and the Indian cobra contains phospholipase A2, which catalyzes the hydrolysis of fatty acids at the C-2 position of glycerophospholipids. The phospholipid breakdown product of this reaction is lysolecithin (lecithin is phosphatidylcholine). At high concentrations, this and other lysophospholipids act as detergents, dissolving the membranes of erythrocytes and lysing the cells. Extensive hemolysis may be life-threatening. (a) All detergents are amphipathic. What are the hydrophilic and hydrophobic portions of lysolecithin? (b) The pain...
