alpha-crotamine is a small toxic protein (42 amino acid residues with three disulphide bridges) present in the venom of Crotallus durissus terrificus. Molecular parameters (Rg = 13.7 A, S = 3,000 A2, V = 9,200 A3 and Dmax = 40 A) were derived from SAXS curves obtained from a solution of this protein at pH = 4.5. An excellent agreement between the experimental distance distribution curve and that calculated from a model consisting of two lobes linked by the Cys(18)-Cys(30) disulphide bridge.
