YncC/McbR are also able to bind to the promoter region of the E. coli K-12 yciGFE genes .
However , the sequence , the length , , relative to the yciGFE promoter , are different in Salmonella , resulting in differential mechanisms of regulation of these genes by YncC/McbR .
However , the position of H-NS binding regions , relative to the yciGFE promoter , are different in Salmonella , resulting in differential mechanisms of regulation of these genes by YncC/McbR .
However , the position of the McbR/YncC , relative to the yciGFE promoter , are different in Salmonella , resulting in differential mechanisms of regulation of these genes by YncC/McbR .
