Five spin labeled derivatives of a neurotoxin from cobra venom were analyzed by the earlier suggested method. The procedure was adjusted to the complex motional behaviour of the label. Each protein derivative carried covalently bound spin label on different lysine residues. In two derivatives, at positions Lys44 and Lys46, the labels were strongly mobile, whereas for other three derivatives modified at Lys15, Lys25 and Lys26 the label was less mobile with respect to the protein molecule, which… CONTINUE READING
