General description
β-Lactamase is a monomeric enzyme of 29 kDa. This product is produced from Enterobacter cloacae and is provided as a lyophilized powder. It acts as a target protein for β-lactam antibiotics. This enzyme is present in Gram-negative bacteria.
Application
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 P4524 is produced from Enterobacter cloacae and is provided as a lyophilized powder.
β-Lactamase from Enterobacter cloacae has been used in the maternal and fetal quantitative blood cultures to avoid any carryover phenomenon. It has also been used as a component in Mueller Hinton (MH) broth for placental cultures.
Biochem/physiol Actions
β--lactamase inactivates β-lactam antibiotics by breaking open the β-lactam ring.
Physical form
Lyophilized powder containing sodium phosphate buffer salts
Analysis Note
Protein determined by biuret.
Other Notes
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.

A cuántas UI corresponde la concentración de 0.2-0.6 UNITS del producto?
1 answer-
The International Unit (I.U.), using benzylpenicillin, is approximately equal to 600 Levy or 75 Pollock units. Also, 1 I.U. is approximately 70,000 kinetic Kersey units. Please also note that 1 I.U. = 1 Sigma unit using benzylpenicillin as a substrate. We have no information regarding the classification of the penicillinase enzymes P0389, P6018, P4399, P4524, and P3553 into groups 2b and group 1 of Bush′s classification system. These enzymes are classified according to Enzyme Nomenclature Biology published by the International Union of Biochemistry and Molecular Biology (IUBMB). The penicillinases and cephalosporinases belong to the EC 3.5.2.6 beta-lactamase, defined as a group of enzymes of varying specificity hydrolyzing β-lactams.
