The mechanism of attack involves a catalytic serine residue, a carboxylated lysine, and another active site serine which contributes to proton movement (A). A high energy tetrahedral intermediate (B) is generated and an acyl enzyme intermediate (C) is formed after the cleavage of the four-membered ring. KCX84 activates the deacylating water which completes the reaction leaving a hydrolyzed β-lactam ring and a regenerated β-lactamase (Powers paper 2013).
