== Publication Abstract from PubMed == | |||
Two species resulting from the reaction of the SHV-1 class A beta-lactamase with the sulfone inhibitor tazobactam have been trapped at 100 K and mapped by X-ray crystallography at 2.0 A resolution. An acyclic form of tazobactam is covalently bonded to the catalytic Ser70 side chain, and a second species, a five-atom vinyl carboxylic acid fragment of tazobactam, is bonded to Ser130. It is proposed that the electron density map of the crystal is a composite picture of two complexes, each with only a single bound species. It is estimated that the two complexes exist in the crystal in approximately equal populations. Results are discussed in relation to the mechanism-based inhibition of class A beta-lactamases by the similar inhibitors sulbactam and clavulanic acid. | |||
