애플리케이션
β--lactamase is used to inactivate β-lactam antibiotics by breaking open the β-lactam ring. β--lactamase is used to study antibiotic resistance and resistance suppression. Product P4399 is produced from Enterobacter cloacae.
생화학적/생리학적 작용
β--lactamase inactivates β-lactam antibiotics by breaking open the β-lactam ring.
단위 정의
One unit will hydrolyze 1.0 μmole of benzylpenicillin per min at pH 7.0 at 25 °C. This International Unit (using benzylpenicillin as substrate) is approximately equal to 600 Levy or 75 Pollock units.

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

New broad-spectrum β-lactamases such as KPC enzymes and CTX-M-15 enzymes threaten to markedly reduce the utility of our armamentarium of β-lactam agents, even our most potent drugs, such as carbapenems. NXL104 is a broad-spectrum non-β-lactam β-lactamase inhibitor. In this evaluation

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
