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

Transcription unit          
Name: dgcZ
Gene(s): dgcZ   Genome Browser M3D Gene expression COLOMBOS
Note(s): Base on a σS-deficient rpoS mutant background, ydeH is under the significant negative control of rpoS Sommerfeldt N,2009 This negative control is most likely due to increased formation of a vegetative or other alternative RNAP holoenzyme in the absence of competition of σS with the other sigma factors Sommerfeldt N,2009 This suggests that σS might control ydeH expression indirectly.
The expression of the gene ydeH is increased when colicin (at 30 ng/ml) is added to the medium 23421615.
Under NlpE outer membrane lipoprotein overexpression, the transcription of the ydeH gene is increased by CpxR Raivio TL,2013
