一般說明
β-内酰胺酶是29 kDa的单体酶。该产品由阴沟肠杆菌生产，以冻干粉形式提供。它可充当β-内酰胺抗生素的靶蛋白。该酶存在于革兰氏阴性菌中。
應用
β-内酰胺酶可通过打开β-内酰胺环来使β-内酰胺抗生素失活。 β-内酰胺酶可用于研究抗生素耐药性和耐药性抑制。 产品P4524由阴沟肠杆菌生产，以冻干粉形式提供。
β-来自阴沟肠杆菌的内酰胺酶已被用于母婴定量血液培养，以避免任何残留现象。它还被用作胎盘培养用Mueller Hinton（MH）肉汤的成分。
生化／生理作用
β-内酰胺酶被用于通过打开 β-内酰胺环灭活β-内酰胺类抗生素。

We present a new hypothesis for the selective pressures responsible for maintaining natural competence and transformation. Our hypothesis is based in part on the observation that in Bacillus subtilis, where transformation is widespread, competence is associated with periods of nongrowth

An efficient synthesis of a 5-fluorouracil-cephalosporin prodrug is described for use against colorectal and other cancers in antibody and gene-directed therapies. The compound shows stability in aqueous media until specifically activated by beta-lactamase (betaL). The kinetic parameters of the 5-fluorouracil-cephalosporin
