Influence of starvation for methionine and other amino acids on subsequent bacterial deoxyribonucleic acid replication.

abstract：:In Pseudomonas aeruginosa, the CbrA/CbrB two-component system is instrumental in the maintenance of the carbon-nitrogen balance and for growth on carbon sources that are energetically less favorable than the preferred dicarboxylate substrates. The CbrA/CbrB system drives the expression of the small RNA CrcZ, which ant...
