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




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


Transcription unit       
Name: pflA
Gene(s): pflA   Genome Browser M3D Gene expression COLOMBOS
Note(s): The expression of the gene pflA is increased under acidic growth conditions in microaerobiosis |CITS:[23274360]|. The increased expression of this gene is in agreement with the increased formate production observed under acidic conditions |CITS:[23274360]|.
