ABSTRACT

Pseudomonas fluorescens SBW25 is capable of growing on histidine as a sole source of carbon and/or nitrogen. Previous work showed that the two-component regulatory system CbrAB is required for expression of the histidine utilization (hut) locus when histidine is the sole source of carbon and nitrogen. Here, using mutational analysis and transcriptional assays, we demonstrate involvement of a second two-component system, NtrBC. When histidine is the sole carbon source, transcri...
