Design of composite inhibitors targeting glutamate carboxypeptidase II: the importance of effector functionalities

Popis výsledku v původním jazyce

Inhibitors targeting human glutamate carboxypeptidase II (GCPII) typically consist of a P1 glutamate-derived binding module, which warrants the high affinity and specificity, linked to an effector function that is positioned within the entrance funnel ofthe enzyme. Here we present a comprehensive structural and computational study aimed at dissecting the importance of the effector function for GCPII binding and affinity. To this end we determined crystal structures of human GCPII in complex with a series of phosphoramidate-based inhibitors harboring effector functions of diverse physicochemical characteristics. Our data show that higher binding affinities of phosphoramidates, compared to matching phosphonates, are linked to the presence of additionalhydrogen bonds between Glu424 and Gly518 of the enzyme and the amide group of the phosphoramidate. While the positioning of the P1 glutamate-derived module within the S1 pocket of GCPII is invariant, interaction interfaces between effecto
