The complete amino acid sequence of a thrombin-like enzyme with gyroxin activity isolated from the venom of the bushmaster snake Lachesis muta muta was determined by automated and DABITC/PITC microsequencing of the intact protein; fragments derived from it by separate cleavages with cyanogen bromide, iodosobenzoic acid and hydroxylamine; and peptides resulting from enzymatic digestions with trypsin, pepsin, chymotrypsin, and elastase. The protein, which is composed of 228 residues, contains four putative sites of N-linked glycosylation and exhibits significant sequence similarities with other serine proteases reported from snake venoms.
