title: Studies of a fibrinolytic enzyme from the larvae of Lonomia achelous (Cramer) using chromogenic peptide substrates.
abstract: A fibrinolytic agent purified from the haemolymph, hair secretion and whole body extract of Lonomia achelous (Cramer) cleaves various chromogenic peptide substrates. The best substrate were found to be pyro-Glu-Gly-Arg-pNA (S-2444) followed by D-Pro-Phe-Arg-pNA (S-2302) and Bz-Ile-Glu-(or) Gly-Arg-pNA (S-2222) designed for urokinase, plasma kallikrein and factor Xa, respectively. Using substrate S-2251 we also found a plasminogen activator.
