Use of Novel Boronic Acid Transition State Inhibitors To Probe Substrate Affinity in SHV-Type Extended-Spectrum β-Lactamases
Boronic acid transition state inhibitors (BATSIs) with R1 side chains of cefotaxime and ceftazidime were assayed against SHV-1, SHV-2, SHV-5, D104K, and D104K G238S β-lactamases. The D104K variant was the most susceptible to inhibition by the ceftazidime BATSI (K(i), 730 ± 80 nM), while the D104K G2...
