Phospholipase c activity
The toxin has phospholipase C activity, and causes hemolysis, lethality, and dermonecrosis. At high concentrations, alpha-toxin induces massive degradation of phosphatidylcholine and sphingomyelin, producing diacylglycerol and ceramide, respectively. These molecules then participate in signal … See more Phospholipase C (PLC) is a class of membrane-associated enzymes that cleave phospholipids just before the phosphate group (see figure). It is most commonly taken to be synonymous with the human forms of this … See more The primary catalyzed reaction of PLC occurs on an insoluble substrate at a lipid-water interface. The residues in the active site are conserved in all PLC isotypes. In animals, PLC … See more PLC cleaves the phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) into diacyl glycerol (DAG) and inositol 1,4,5-trisphosphate (IP3). Thus PLC has a profound impact on the depletion of PIP2, which acts as a membrane anchor or allosteric regulator … See more Mammalian variants The extensive number of functions exerted by the PLC reaction requires that it be strictly regulated and able to respond to multiple extra- and … See more In mammals, PLCs share a conserved core structure and differ in other domains specific for each family.
