Comparative study of the nucleophilic attack step in the proteases catalytic activity: A theoretical study
The nucleophilic attack step of the hydrolysis reaction mechanism of the glycine-glycine peptide bond mediated by the enzymatic action of various proteases was elucidated by means of DFT calculations. Five different protease models were considered; namely: cysteine (Cys), threonine (Thr), serine (Ser), aspartyl (Asp) proteases, and a metalloprotease containing zinc (Zn). The model was simplified in order to gain information about the nucleophilic attack in this type of reaction. As a comparative study, this work is focused on the trend in the reactivity of the models. According to the computed activation energies, the reactivity order was determined as follows Cys < Thr < Ser < Zn < Asp, being in all cases faster than the uncatalysed spontaneous hydrolysis. A further analysis of the reactions by means of the reaction force approach showed that the structural changes accounts for 65-90% of the total activation energy. Moreover, a natural bond orbital analysis allows the reactions to be classified as synchronous with a late transition state for all cases. Systems analogous to the Cys-protease can be proposed as a promising candidate for the design of mimetic systems capable to cleavage amide bonds. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
