分子機能: Leupeptin is a competitive inhibitor of serine and cysteine proteases reversibly. Leupeptin inhibits serine proteinases, trypsin, plasmin, porcine kallikrein, and cysteine proteinases, papain, cathepsin B, endoproteinase Lys-C. It does not inhibit chymotrypsin or thrombin. / 情報源: Wikipedia

分子機能: The discovery of leupeptin in the late 1960s drew attention to the potential of aldehydes as peptidase inhibitors.Many aldehydes are now known as inhibitors of serine, cysteine or threonine peptidases. They form hemiacetal orthiohemiacetal conjugates with the essential hydroxyl or thiol group of the enzyme that are transition state analogues.The compounds exist predominantly in their hydrated forms in aqueous solution, but only the aldehyde is an effectiveinhibitor. Aldehydes can also act as inhibitors of metallopeptidases. Leupeptin is a slow, tight-binding, transitionstate analogue inhibitor of cathepsin B. Leupeptin inhibits a wide range of serine (families S1, S8), cysteine(families C1, C11) and threonine (family T1) peptidases. Apart from numerous peptidases in families S1 and C1,leupeptin is a potent inhibitor of clostripain C11.001 and PACE4 S08.075 and the trypsin-like activity of theproteasome T01.011 / 情報源: MEROPS
