phoA-psiF operon and associated TUs in Escherichia coli K-12 genome




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


Transcription unit          
Name: phoA-psiF
Synonym(s): OP00071, phoA
Gene(s): phoA, psiF   Genome Browser M3D Gene expression COLOMBOS
Note(s): The expression of the gene phoA is increased under phosphate starvation 30765722 and acidic growth conditions in aerobiosis but not in microaerobiosis Marzan LW,2013 The increased expression appears to be caused by the transcription factor PhoB Marzan LW,2013
