Transcription unit          
Name: cydAB
Synonym(s): OP00140
Gene(s): cydA, cydB   Genome Browser M3D Gene expression COLOMBOS
Note(s): The cydAB operon is upregulated by long-term (8 to 12 h) exposure of E. coli to some biocides 32385082.
The expression of the gene cydB is increased under acidic growth conditions in either aerobiosis or microaerobiosis Marzan LW,2013 The increased expression under aerobiosis appears to be caused by the transcription factor PhoB Marzan LW,2013
