amecA = gene encoding PBP 2a, the penicillin-binding protein with low binding affinity that mediates methicillin resistance; mecR1-mecI = sensor-transducer and repressor genes that regulate production of inducible PBP 2a; ccrAB = cassette chromosome recombinases A and B that mobilize the mec element; pUB110 = integrated plasmid that encodes tobramycin and kanamycin resistance; IS431 = insertion sequence; Tn554 = erythromycin-resistance encoding transposon; Tc = tetracycline-resistance determinant; Hg = mercury-resistance determinant.
