Isolation of a Postynaptic Blocker from the Venom of the Green Mamba, Dendroaspis angusticeps
نویسنده
چکیده مقاله:
A blocker of postsynaptic acetylcholine receptors was isolated from venom of the Eastern green mamba Dendroaspis angusticeps, by gel filtration, ion-exchange and reverse phase high performance liquid chromatography. The isolated component blocks neuromuscular transmission and responses to exogenously applied acetylcholine in isolated chick biventer cervices preparations. These results suggest that postsynaptic blockers exist in venoms of all members of the Dendroaspis genus.

Two structurally related (48.6% amino acid sequence identity) peptides with cytotoxic activity against human non-small cell lung adenocarcinoma A549 cells were purified from the venom of the Eastern green mamba Dendroaspis angusticeps using reversed phase HPLC. The peptides were identified as members of the three-finger superfamily of snake toxins by mass fingerprinting of tryptic digests. The ...

UNLABELLED A toxicovenomic study was performed on the venom of the green mamba, Dendroaspis angusticeps. Forty-two different proteins were identified in the venom of D. angusticeps, in addition to the nucleoside adenosine. The most abundant proteins belong to the three-finger toxin (3FTx) (69.2%) and the Kunitz-type proteinase inhibitor (16.3%) families. Several sub-subfamilies of the 3FTxs wer...
