title: Biochemical Characterization of SFC-1, a class A carbapenem-hydrolyzing beta-lactamase.
abstract: The carbapenem-hydrolyzing beta-lactamase SFC-1 from Serratia fonticola UTAD54 was overexpressed in Escherichia coli, purified, and characterized. The enzyme exhibited an apparent molecular mass of 30.5 kDa, determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. SFC-1 hydrolyzes penicillins, cephalosporins, aztreonam, and carbapenems and is inhibited by clavulanic acid, sulbactam, and tazobactam.
