Two CMY-2 derivatives, CMY-31 (Gln215->Arg) from Salmonella enterica serotype Newport and CMY-36 (Ala77->Cys and Gln193->Glu) from Klebsiella pneumoniae, were characterized. Both cephalosporinases functionally resembled CMY-2. blaCMY alleles occurred as parts of a putative transposon comprising ISEcp1B and a Citrobacter freundii-derived sequence carried by ColE1-like plasmids similar to CMY-5-encoding pTKH11 from Klebsiella oxytoca.
