일반 설명
Penicillinase from Bacillus cereus has been shown to contain three distinct species when purified and examined for homogeneity by sedimentation analysis, amino-terminal analysis, and vertical acrylamide gel electrophoresis.
애플리케이션
Penicillinase can be used to reduce levels of penicillin in patients with severe penicillin reactions.
Used in the production of penicillin.
Used in the production of penicillin. Penicillinase from Bacillus cereus has been used in a comparison study with penicillinase from Bacillus subtillis where the Michaelis constant, shape of the Ph/activity curve and immunological properties were shown to be significantly different.
생화학적/생리학적 작용
Penicillinase specifically catalyzes the hydrolysis of β-lactam ring of penicillin.
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.
물리적 형태
Lyophilized powder containing phosphate and citrate buffer salts
분석 메모

Large-scale population screening for early and accurate detection of disease is a key objective for future diagnostics. Ideally, diagnostic tests that achieve this goal are also cost-effective, fast and easily adaptable to new diseases with the potential of multiplexing. Mass

Aspergillus oryzae penicillin biosynthetic genes were clustered. The penicillin production was positively regulated by VeA, a global gene regulator required for transcriptional expression of the penicillin biosynthetic genes. Overexpression of the biosynthetic genes by a strong promoter yielded a greater
