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


Transcription unit          
Name: fdhF
Synonym(s): OP00207
Gene(s): fdhF   Genome Browser M3D Gene expression COLOMBOS
Note(s): This transcription unit is repressed and induced anaerobically. It is repressed in the presence of nitrate and induced in the presence of formate Wang H,2003
Based on qRT-PCR, it was found that three selenopolypeptide genes, fdnG, fdoG, and fdhF, were induced more than 2-fold by both 0.01 and 5 mM Na2SeO3 (sodium selenite) Campagne S, Marsh ME, Capitani G, Vorholt JA, Allain FH,2014
