ABSTRACT
Objective To purify AmpC beta-lactamase from Enterobacter cloacae and study its physical and chemical characteristics.Methods The bacteria were fragmentized by ultrasonication and AmpC beta-lactamase was purified by ion-exchange.The properties of the purified enzyme,such as molecular weight and isoelectric point were determined by electrophoresis.Results The purified AmpC beta-lactamase was obtained and its specificity to substrate was sufficient for classification of class C cephalosporinase.Conclusion AmpC can be successfully purified from Enterobacter cloacae and is effective for application.
