일반 설명
Penicillinase from Bacillus cereus is both an extracellular and cell-bound enzyme. It has a single polypeptide chain and has a molecular weight of 31 kDa. It lacks cysteine in the protein sequence.
애플리케이션
Penicillinase from Bacillus cereus may be used in the preparation of biosensor for amperometric detection of hydrolysis of penicillin.
Used in the production of penicillin.
생화학적/생리학적 작용
Penicillinase specifically catalyzes the hydrolysis of β-lactam ring of penicillin.
포장
Bottomless glass bottle. Contents are inside inserted fused cone.
단위 정의
One unit will hydrolyze 1.0 μmole of indicated substrate per min at pH 7.0 at 25 °C. Sold as benzylpenicillin units. This International Unit (using benzylpenicillin as substrate) is approximately equal to 600 Levy or 75 Pollock units.
기타 정보
Used to destroy β-lactam antibiotics in body fluids or culture media. For the determination of penicillin; In the coupled enzyme assay for isopenicillin N synthetase; ELISA of estradiol; Penicillinase optodes

The development of a coupled enzyme assay for the determination of isopenicillin N synthetase activity in purified extracts from Cephalosporium acremonium was described. Isopenicillin N formed from its precursor, delta-(L-alpha-aminoadipyl)-L-cysteinyl-D-valine (ACV), by the synthetase was hydrolyzed by beta-lactamase I to
