| pubmed-article:494946 | pubmed:abstractText | Porcine elastase II (EC 3.4.21.-), a pancreatic proteinase with elastolytic activity, hydrolyses the oxidized beta-chain of insulin with major cleavages occurring at Leu17-Val18, Phe24-Phe25, Phe25-Tyr26 and Tyr26-Thr27. Canine leucocytic elastase splits the same substrate with major sites at Val12-Glu13 and Val18-Cys19 O3H. This indicates similarity of elastase II to chymotrypsins (EC 3.4.21.1 or 3.4.21.2) and of dog leucocyte enzyme to human granulocyte elastase and porcine pancreatic elastase I (EC 3.4.21.11). | lld:pubmed |
