Function

Class B beta-lactamase which confers resistance to the beta-lactam antibiotics, including penicillins, cephalosporins and carbapenems. Acts via hydrolysis of the beta-lactam ring. Has penicillin-, cephalosporin- and carbapenem-hydrolyzing activities.

Product Specifications

Recombinant Serratia marcescens Metallo-beta-lactamase type 2, partial is a recombinant protein, expressed in E.coli, covering amino acids 20-246aa, with N-terminal 10XHis-SUMO-tagged and C-terminal Myc-tagged tag, purity Greater than 90% as determined by SDS-PAGE..
