Structural features associated with the ability of a monoclonal antibody (mAb) to discriminate between protein variants are identified and engineered. The variants are the curaremimetic toxin alpha from Naja nigricollis and erabutoxin a or b from Laticauda semifasciata, which differ

We have inserted a disulfide-containing snake neurotoxin into the N-terminal end of Escherichia coli alkaline phosphatase, between residues +6 and +7 of the mature enzyme. For this purpose, we have designed a cloning and expression vector which allows insertion of

1. Erabutoxin b was reduced, S-carboxymethylated and hydrolysed with trypsin. Seven tryptic fragments were isolated by column chromatography and paper electrophoresis. Some of the fragments were further hydrolysed with alpha-chymotrypsin, pepsin, Nagarse, Proctase A or Proctase B. The amino acid

Although previous results indicate that alpha-subunit residues Trp(187), Val(188), Phe(189), Tyr(190), and Pro(194) of the mouse nicotinic acetylcholine receptor are solvent-accessible and are in a position to contribute to the alpha-bungarotoxin (alpha-Bgtx) binding site (Spura, A., Russin, T. S., Freedman

Curaremimetic toxins are typical non-enzymatic toxins that bind to their target [the nicotinic acetylcholine receptor (AChR)] through multiple residues. Nevertheless, we show that the concomitant substitutions of only three of the ten functionally important residues of such a toxin sufficed
