RegulonDB RegulonDB 11.1: Operon Form
   

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




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


Transcription unit       
Name: mobAB
Gene(s): mobB, mobA   Genome Browser M3D Gene expression COLOMBOS
Note(s): The expression of the mobAB operon is very low and apparently constitutive.
FNR represses mobB gene expression under anaerobiosis, but it is not known which of the two promoters transcribing the gene is affected, or even if this regulation is direct or indirect Salmon K,2003.
A putative DNA-binding site for NsrR was identified upstream of the mobA gene Fujita D,2021.
Evidence: [EXP-IEP] Inferred from expression pattern
[EXP-IEP-COREGULATION] Inferred through co-regulation
Reference(s): [1] Iobbi-Nivol C., et al., 1995
Promoter
Name: mobAp1
+1: 4042030
Distance from start of the gene: 31
