A molecular model of the active site of the serine protease dipeptidyl peptidase IV (DPP IV or CD26) has been developed on the basis of comparative molecular field analysis (CoMFA) of competitive inhibitors and by force field calculations. By application of CoMFA experimentally obtained inhibition constants Ki have been successfully predicted. The resulting steric and electrostatic coefficients of CoMFA were used for the development of the molecular model. The main assumptions of the model are the recognition of substrates or inhibitors by the side chains of a tyrosine (S1-position) and a tryptophan residue (S2-position). The model helps us to understand a multitude of experimental data regarding the substrate specificity of this enzyme as well as results obtained by genetic engineering experiments by other authors. General conclusions concerning a new family of serine proteases are drawn and discussed.
