RegulonDB RegulonDB 10.7: Operon Form
   

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




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


Transcription unit          
Name: grxA
Gene(s): grxA   Genome Browser M3D Gene expression COLOMBOS
Note(s): The transcription of the gene grxA is enhanced under high oxygen saturation (300%) in the absence of the superoxide dismutase proteins SodA and SodB |CITS:[ 23497217]|.
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 |CITS:[31421411]|.
