Effects of overexpression of the metD operon on uptake of 1-[14C]L- methionine (A) and 1-[14C]D-methionine (B) by the wild type, the abc-yaeE and the yaeC mutant. Bacteria were grown in M9 minimal medium plus ampicillin and arabinose at 100 g/ml and 2 mM, respectively. Uptake was performed as described in Figure 2. , wild type BW25113 (pBAD24); , wild Type BW25113 (pBAD24-metD); , abc-yaeE (pBAD24); , abc-yaeE (pBAD24-metD); , yaeC (pBAD24); and ,yaeC (pBAD24-metD).
