Irreversible inhibition คือ
In biochemistry, suicide inhibition, also known as suicide inactivation or mechanism-based inhibition, is an irreversible form of enzyme inhibition that occurs when an enzyme binds a substrate analog and forms an irreversible complex with it through a covalent bond during the normal catalysis reaction. The inhibitor binds to the active site where it is modified by the enzyme to prod… WebE-64 is a potent irreversible inhibitor against general cysteine proteases, and its binding modes with papain, actinidin, cathepsin L, and cathepsin K have been reviewed at the …
