Irreversible inhibitor 意味
WebJun 15, 2012 · Nonspecific irreversible inhibitors can react with several groups of the same type in different proteins. Specific irreversible inhibitors form an initial noncovalent complex with the enzyme before the reaction within that complex to form a covalent bond. Active-site-directed inhibitors contain a reactive grouping attached to a substrate analogue. WebReversible inhibitors are not covalently bound to enzymes but irreversible inhibitors are. Irreversible inhibitors are easier to purify from solutions of enzymes than reversible inhibitors. Enzyme activity can be restored by adding more substrate with irreversible inhibitors, but not reversible inhibitors. All the above are true.
