Which are the isoenzymes of phospholipase A2?

Answer 1

>>Secretory PLA2 (sPLA2) have low molecular weights, require millimolar Ca2+ concentrations for activity, and are secreted into the extracellular space.

>>The cytosolic PLA2 (cPLA2) has a molecular mass of 85 kDa, requires increases in intracellular Ca2+ for phosphorylation of the enzyme and translocation to intracellular membranes but does not require Ca2+ for its catalytic activity.

>> The Ca2+-independent PLA2 (iPLA2) has a molecular mass of 80 kDa and does not require Ca2+ for activity.♥
