The assignment of the 1H nuclear magnetic resonance (n.m.r.) spectrum of the trypsin inhibitor homologue K from the venom of Dendroaspis polylepis polylepis is described and documented. The assignments are based entirely on the amino acid sequence and on 2-dimensional n.m.r. experiments at 360 and
The potassium channel blocker dendrotoxin I was acetylated with acetic anhydride. Mono-acetyl derivatives of all seven lysine residues (N-terminus blocked) and a di-derivative were isolated by chromatography on the cation-exchanger Bio-Rex 70 and reversed-phase high-performance liquid
We report the characterization, by combination of high-resolution on-line molecular mass and disulfide bond profiling and top-down MS/MS analysis, of the venom proteomes of two congeneric African snake species of medical importance, Dendroaspis angusticeps (green mamba) and D. polylepis (black
