摘要
The ydfHI genes encode a sensor kinase and a response regulator forming a two-component system. ydfJ is located downstream of ydfHI, and belongs to the RND (resistance-nodulation-cell division) superfamily, which is present in most major organisms. Four genes (secDF, yerP, ydfJ and ydgH) in Bacillus subtilis belong to this family. This study revealed that the YdfHI two-component system regulates ydfJ transcription. A gel shift assay using histidine-tagged YdfI (h-YdfI) showed that it directly binds to the ydfJ promoter region. Moreover, DNase I footprinting analysis revealed a tandem repeat sequence consisting of two conserved 12-mer sequences (GCCCRAAYGTAC) within the h-YdfI-binding site.
