| additional information | recombinant enzymes, as well as whole venoms from diverse Loxosceles species, exclusively catalyze transphosphatidylation rather than hydrolysis, forming cyclic phosphate products from both major substrates, e.g. 1-palmitoyl-sn-glycero-2,3-cyclic-phosphate. Cyclic phosphates have vastly different biological properties from their monoester counterparts, and they may be relevant to the pathology of brown spider envenomation | Loxosceles reclusa | ? | - |
