TPCK is an irreversible inhibitor of chymotrypsin. Also inhibits some cysteine proteases such as caspase, papain, bromelain or ficin. It does not inhibit trypsin or zymogens. TPCK is observed covalently bound in the active site of Caspase 3 in the crystal structure of the complex solved in 2010. The chloromethyl group reacts with the active site cysteine to form a covalent bond with the loss of the chlorine. Splet23. mar. 1971 · Chymotrypsin was also treated with a specific inhibitor for trypsin, L-Ichloro-3-tosylamido-7-amino-2-heptanone (TLCK)5, obtained from Cyclochemical.
