RegulonDB RegulonDB 10.10: Operon Form
   

trxC operon and associated TUs in Escherichia coli K-12 genome




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


Transcription unit          
Name: trxC
Gene(s): trxC   Genome Browser M3D Gene expression COLOMBOS
Note(s): The transcription of the gene trxC is enhanced under high oxygen saturation (300%) in the absence of the superoxide dismutase proteins SodA and SodB Baez A,2013
Sulfane sulfur modifies OxyR at Cys199 to form a protein persulfide that in turn activates the expression of grxA, trxC, and katG promoters under both aerobic and anaerobic conditions Hou N, Yan Z, Fan K, Li H, Zhao R, Xia Y, Xun L, Liu H,2019
