Atrolysin A
Atrolysin A (EC 3.4.24.1, Crotalus atrox metalloendopeptidase a, hemorrhagic toxin a, Crotalus atrox alpha-proteinase, Crotalus atrox proteinase, bothropasin) is an enzyme.[1][2][3][4] This enzyme catalyses the following chemical reaction
- Cleavage of Asn3-Gln, His5-Leu, His10-Leu, Ala14-Leu and Tyr16-Leu in insulin B chain; removes C-terminal Leu from small peptides
This endopeptidase is one of six hemorrhagic toxins in the venom of western diamondback rattlesnake.
