This page displays every known transcription unit of this operon and their known regulation.


Transcription unit          
Name: argCBH
Synonym(s): OP00005
Gene(s): argC, argB, argH   Genome Browser M3D Gene expression COLOMBOS
Note(s): argCBH is also controlled by RpoS during the entry into the stationary phase. However, 16504055 could not determined if the rpoS effect was direct or indirect.
Based on DNA microarray analysis, the mechanism of bacterial inactivation by carvacrol and citral was studied 28644990. Treatment by both compounds caused membrane damage and activated metabolism through the production of nucleotides required for DNA and RNA synthesis and metabolic processes 28644990. A total of 76 and 156 genes demonstrated significant transcriptional differences by carvacrol and citral, respectively. Genes upregulated by carvacrol treatment included the multidrug efflux pump genes acrA and mdtM, genes related to the phage shock response, pspA, pspB, pspC, pspD, pspF, and pspG, and genes whose products are important for biosynthesis of arginine (argC, argG, artJ) and purine nucleotides (purC, purM). Genes upregulated by citral treatment included purH, pyrB, and pyrI. On the other hand, mutations in several differentially expressed genes confirmed the roles of ygaV, yjbO, pspC, sdhA, yejG, and ygaV in mechanisms of inactivation by carvacrol and citral 28644990.
