Molecular Specificities of R Factor-Determined Beta-Lactamases: Correlation with Plasmid Compatibility

Beta (β)-lactamases determined by 29 ampicillin resistance plasmids could be divided into two types. One, TEM-type, was very uniform with respect to substrate specificity but heterogeneous in absolute levels of β-lactamase activity. The TEM-type β-lactamase was determined by R factors of compatibili...
