RegulonDB RegulonDB 10.9: Operon Form
   

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




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


Transcription unit          
Name: dadAX
Gene(s): dadA, dadX   Genome Browser M3D Gene expression COLOMBOS
Note(s): The transcript of dadAX is decreased after σE induction, as observed in high-throughput analysis of gene expression Lacoux C,2020.
dadAX operon expression is upregulated upon L-valine addition (isoleucine starvation) in the cellular growth medium 32211022.

A potential RNA G-quadruplex structure, formed by guanine-rich sequences located in the coding sequence region of the gene, was identified for dadA . This structure could regulate the expression of the gene, as observed for hemL gene expression 31964733.

Note(s): This is the +1 in induced cells; in uninduced cells transcription starts 5 bp dowstream: GATTAGA-(here). Several regions with significant similarity to known σ70 promoter sequences were found. Previous genetic studies identified a dadR gene as a cis-acting regulatory region of the dad operon. Therefore, the dadR region may contain promoter and regulatory sequences of the dad operon. The DNA fragment of about 260 bp preceding dadA should correspond to dadR.

Transcription unit          
Name: dadAX
Gene(s): dadA, dadX   Genome Browser M3D Gene expression COLOMBOS
Note(s): dadAX operon expression is upregulated upon L-valine addition (isoleucine starvation) in the cellular growth medium 32211022.
A potential RNA G-quadruplex structure, formed by guanine-rich sequences located in the coding sequence region of the gene, was identified for dadA . This structure could regulate the expression of the gene, as observed for hemL gene expression 31964733.
