| - | [[Category: | + | [https://www.uniprot.org/uniprot/BIB11_SICTE BIB11_SICTE] Dermonecrotic toxins cleave the phosphodiester linkage between the phosphate and headgroup of certain phospholipids (sphingolipid and lysolipid substrates), forming an alcohol (often choline) and a cyclic phosphate (PubMed:25752604). This toxin acts on lysophosphatidylethanolamine (LPE) and ceramide phosphoethanolamine (CPE) with high activity (PubMed:25752604). This toxin acts on sphingomyelin (SM) with very low activity and is not active on lysophosphatidylserine (LPS), lysophosphatidylcholine (LPC) and lysophosphatidylglycerol (LPG) (PubMed:25752604). It acts by transphosphatidylation, releasing exclusively cyclic phosphate as second products (PubMed:25752604). It is not surprising that spider toxins have affinity for ethanolamine-containing sphingolipids since they are common in insect prey (PubMed:25752604). Induces dermonecrosis, hemolysis, increased vascular permeability, edema, inflammatory response, and platelet aggregation (By similarity).[UniProtKB:P0CE80]<ref>PMID:25752604</ref> |
