| unusual venom phospholipases a2 of two primitive tree vipers trimeresurus puniceus and trimeresurus borneensis. | to explore the venom diversity of asian pit vipers, we investigated the structure and function of venom phospholipase a2 (pla2) derived from two primitive tree vipers trimeresurus puniceus and trimeresurus borneensis. we purified six novel pla2s from t. puniceus venom and another three from t. borneensis venom. all cdnas encoding these pla2s except one were cloned, and the molecular masses and n-terminal sequences of the purified enzymes closely matched those predicted from the cdna. three conta ... | 2005 | 15955061 |
