Human Carbonic Anhydrase II complexed with two-prong inhibitors

Contents 1 Overview 2 Disease 3 About this Structure 4 Reference

Overview

The atomic-resolution crystal structures of human carbonic anhydrases I, and II complexed with "two-prong" inhibitors are reported. Each inhibitor, contains a benzenesulfonamide prong and a cupric iminodiacetate, (IDA-Cu(2+)) prong separated by linkers of different lengths and, compositions. The ionized NH(-) group of each benzenesulfonamide, coordinates to the active site Zn(2+) ion; the IDA-Cu(2+) prong of the, tightest-binding inhibitor, BR30, binds to H64 of CAII and H200 of CAI., This work provides the first evidence verifying the structural basis of, nanomolar affinity measured for two-prong inhibitors targeting the, carbonic anhydrases.
