CMY2-MIR-ACT-EC family cephalosporin-hydrolyzing class C beta-lactamase
This narrowly defined subfamily of AmpC class C beta-lactamases covers chromosomal ly encoded proteins apparently restricted to and universal in Klebsiella (previously Enterobacter) aerogenes. Strains encoding this enzyme tend to be resistant to penicillins and first and second generation cephalosporins.
