Note(s): The mdtEF-tolC, malEFG, gadBC, treBC, entCEBA-ybdB, hdeAB-yhiD, and alaE operons were differentially regulated after induction of the nonnative organic acid citramalate Webb J,2019
Evidence: [CV(LTED/PM)] cross validation(LTED/PM)
[IEP] Inferred from expression pattern
[ITCR] Inferred through co-regulation
[LTED] Length of transcript experimentally determined
[PM] Polar mutation

Promoter
Name: treBp
+1: 4466210
Sigma Factor: Sigma70 Sigmulon
Distance from start of the gene: 30

Note(s): The activity of this promoter appears to be decreased in the presence of σE. It is repressed during the first 5 minutes following σE induction and decreased from 5 to 10 minutes and from 10 to 20 minutes after induction of the σ factor Lacoux C,2020.
