The positive charge of Lys27 was suppressed by chemical means in two short-chain curaremimetic toxins, namely erabutoxin a (Ea) from Laticauda semifasciata and toxin alpha from Naja nigricollis. This modification leads to a decrease in the binding affinity of the

To study the site by which erabutoxin a (Ea) from Laticauda semifasciata binds to the nicotinic acetylcholine receptor, we mutated most residues that are shared with other curaremimetic toxins and studied the structural and biological consequences of introduced mutations. By

The three-dimensional structure of erabutoxin a, a single-chain, 62-residue protein neurotoxin from snake venom, has been determined to 2.0-A resolution by x-ray crystal structure analysis. Molecular replacement methods were used, and the structure refined to a residual R = 0.17.

Recombinant erabutoxin a (Ea(r)) has been crystallized by vapour diffusion in hanging drops. The crystals belong to space group P2(1)2(1)2(1) with cell dimensions a = 55.8 A, b = 53.4 A, c = 40.8 A. Diffraction data have been recorded

The aim of this work was to produce and to label snake neurotoxins, disulfide-rich proteins. A mutant of a snake toxin, erabutoxin a, was used as a model. Its N-terminal part was fused to ZZ, a synthetic IgG-binding domain of
