the protease had about 429 amino acid residues , and the first 20 amino-terminal amino acid residues were ala-gln-ala-asn-gly-thr-gly-pro-gly-gly-asn-ser-lys-thr-gly-arg-tyr-glu- phe-gly . the purified protease was toxic for mice ( about 1.5 mg kg-1 and 4.5 mg kg-1 , intraperitoneal and intravenous ld50 values , respectively ) , and subcutaneous injection of the enzyme elicited rapid and extensive dermonecrosis .
