It will bind to the enzyme using a covalent bond at the active site … WebNov 12, 2024 · Abstract. Irreversible inhibition of enzyme activity often results from covalent modification of the enzyme protein. Once the enzyme is covalently bound to an irreversible inhibitor, it is permanently incapacitated. The inhibition is time-dependent and not freely reversible by procedures like dilution, dialysis, or gel filtration. chippy armagh
