RT "Isolation and complete amino acid sequence of two fibrinolytic proteinases
RT from the toxic Saturnid caterpillar Lonomia achelous.";
RL Biochim. Biophys. Acta 1079:214-221(1991).
CC -!- FUNCTION: Fibrinolytic activity; shows preferential cleavage of Arg-Gly
CC bonds in all three fibrinogen chains. Contact with the caterpillars
CC causes severe bleeding, due the anticoagulant effect of the protein.
CC {ECO:0000269|PubMed:1911844}.
CC -!- ACTIVITY REGULATION: Sensitive to serine proteinase inhibitors and
CC thiol proteinase inhibitors. {ECO:0000269|PubMed:1911844}.
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space
CC {ECO:0000269|PubMed:1911844}.
CC -!- TISSUE SPECIFICITY: Hemolymph and saliva of the larval form
CC (caterpillar). {ECO:0000269|PubMed:1911844}.
CC -!- SIMILARITY: Belongs to the peptidase S1 family. {ECO:0000255|PROSITE-
CC ProRule:PRU00274}.
