Additional file 1 of In vitro conjugation kinetics of AmpC, broad spectrum and extended-spectrum beta-lactamase-producing Escherichia coli donors and various Enterobacteriaceae recipients
*nd, not determined; however, it was confirmed that all mutants were activated by maltose like RG13 using nitrocefin assays (100 µM nitrocefin) in the presence and absence of maltose.
TEM-52, differing from TEM-1 by having the substitutions Glu-104→Lys, Met-182→Thr, and Gly-238→Ser, has previously been described as the most prevalent extended-spectrum β-lactamase (ESBL) in Korea. I
