RegulonDB RegulonDB 10.9: Operon Form
   

edd-eda operon and associated TUs in Escherichia coli K-12 genome




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


Transcription unit          
Name: eda
Gene(s): eda   Genome Browser M3D Gene expression COLOMBOS
Note(s): Under nitrogen-rich growth conditions, the expression of the eda gene was increased in mutants for two genes that encode two terminal oxidases, cyoA and cydB, and in a mutant of the transcriptional regulator Fur. However, it is unknown if the effects of the transcriptional regulators act directly on gene expression; also, it is unknown which of the four promoters that transcribe the gene could be regulated by the regulators Kumar R,2011

Note(s): The expression of the operon edd-eda is increased under acidic growth conditions in microaerobiosis Marzan LW,2013
A potential RNA G-quadruplex structure, formed by guanine-rich sequences located in the coding sequence region of the gene, was identified for edd . This structure could regulate the expression of the gene, as observed for hemL gene expression 31964733.
