Competitive serine protease inhibitor
|Alternate Names||Antagosan; Anikrein; Antilysin(e); Basic pancreatic trypsin inhibitor; BPTI; Bayer A 128; Kallikrein-trypsin inactivator; Fosten; Iniprol; Kunitz protease inhibitor; Onquinin; Repulson; RP-9921; Ryker 52G; Trasylol; Triazinin; Zymofren|
|Base Catalog Number||191158|
|Biochemical Physiological Actions||Aprotinin is a competitive serine protease inhibitor that inhibits trypsin, chymotrypsin, kallikrein and plasmin. Aprotinin forms stable complexes with and blocks the active sites of enzymes. Binding is reversible with most aprotinin-protease complexes dissociating at pH >10 or < 3.|
