摘要：

Benzylpenicillin methyl phosphate (BPMP, 1), hydrolyzes slowly to produce benzylpencillin and methyl phosphate. BPMP is a substrate and inactivator of E coli RTEM beta-lactamase. A competitive inhibitor of beta-lactamase protects the enzyme from inactivation by BPMP. It is proposed that BPMP acylates the epsilon-amino group of Lys-234 of the enzyme.
