Description
Analysis Note Another commonly used unit of activity is the KIU (Kallikrein Inhibitor Unit).
1 TIU ∼ 1,300 KIU.
Biochem/physiol 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. Effective concentration equimolar with protease.
General description Aprotinin is a protein consisting of 58 amino acids, arranged in a single polypeptide chain that is crosslinked by three disulfide bridges.
Unit Definition 1 U corresponds to 1 biological kallikrein inhibitor unit (KIU)
