Enzyme Function FUNCTION: Snake venom serine protease with tyrosine-specific chymotrypsin-like activity. Hydrolyzes the N-acetyl-L-tyrosine ethyl ester (ATEE). Has weak fibrinogenolytic activity. Weakly hydrolyzes azocasein, Aalpha-chain (FGA) and more slowly Bbeta-chain (FGB) of fibrinogen. Optimal substrates are angiotensins I and II (AGT). {ECO:0000269|PubMed:20950666}.
