We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

[[http://www.uniprot.org/uniprot/PA2B_VIPAE PA2B_VIPAE]] Heterodimer: postsynaptic neurotoxin. Monomer: snake venom phospholipase A2 (PLA2) that shows hemolytic activity and inhibition of platelet aggregation. The hemolytic activity occurs only in presence of fatty acids (unsaturated fatty acids facilitate induce a strong hemolytic activity, whereas saturated fatty acids induce a slight activity). The inhibition of platelet aggregation is almost maximal when aggregation is induced by collagen, and arachidonic acid, whereas it is only of 30% when the aggregation is induced by ADP. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.
