The inactivation of beta-lactamase I by preparations of 6alpha-bromopenicillanic acid showed unexpected kinetic features that indicated that the active species was the 6beta-epimer. Samples containing 6beta-bromopenicillanic acid have been synthesized and shown to inactivate the enzyme in a rapid stoicheiometric reaction.
用6α-溴青霉烷酸制剂使β-内酰胺酶I失活呈现出意想不到的动力学特征,这表明活性物质是6β-差向异构体。已合成了含有6β-溴青霉烷酸的样品,并表明其在快速化学计量反应中使该酶失活。
