Crystal Structure Analysis of Clostridium perfringens alpha-Toxin Isolated from Avian Strain SWCP
Template:ABSTRACT PUBMED 12009886
Function
[PHLC_CLOPF] Bacterial hemolysins are exotoxins that attack blood cell membranes and cause cell rupture. Constitutes an essential virulence factor in gas gangrene. Binds to eukaryotic membranes where it hydrolyzes both phosphatidylcholine and sphingomyelin, causing cell rupture. The diacylglycerol produced can activate both the arachidonic acid pathway, leading to modulation of the inflammatory response cascade and thrombosis, and protein kinase C, leading to activation of eukaryotic phospholipases and further membrane damage.
About this Structure
