Close-up on the carboxylate binding sites of BlaC crystal structures 5NJ2, chain A (a) and 5OYO chain B (b). Several catalytically important residues and a conserved active site water molecule are indicated. Distances (in Å) of proposed hydrogen bridges (purple dashed lines) involving the phosphate group and acetate are indicated in red. The mesh shows the 2Fo – Fc electron density map contoured at 1.5σ (a) or 1.0σ (b).
