[Suggested interrelationships of RNA-polymerase sigma S subunit and nitrogen control system in Pseudomonas chlororaphis].

Abstract excerpt

The effect of mutation in rpoS gene encoding sigma S subunit of RNA-polymerase on the capacity of Pseudomonas chlororaphis 449 to assimilate nitrogen was investigated. It has been shown that mutant cells with knocked-out rpoS gene had significantly lower capacity to utilize the nitrogen sources such as alanine, proline, histidine, arginine, urea, and ammonium and glutamine synthetase was downregulated in their...
