It inhibits the enzymatic activity of RV-4 in vitro but potentiates its lethal potency and neurotoxicity. It may facilitate the specific binding of RV-4 to its presynaptic binding sites, probably by acting as a chaperon, minimizing distraction and destruction of RV-4 en route to the site of action by reducing non-specific binding to muscle and other organs. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.<ref>PMID:8835338</ref> | ||
