Name: rutABCDEFG
Gene(s): rutG, rutF, rutE, rutD, rutC, rutB, rutA   Genome Browser M3D Gene expression COLOMBOS
Evidence: [PAGTSBP] Products of adjacent genes in the same biological process

Promoter
Name: rutAp
+1: 1074026
Sigma Factor: Sigma54 Sigmulon
Distance from start of the gene: 15
Sequence: aacagattaataacattaactttttaaaaactggcatccgctttgcaaacaagccaatacGcggctgaaaaggatatgcag

Note(s): This promoter was identified by microarray and ChIP assays with a mutant
σ54 strain and a σ54-overexpressing strain,
and by σ54-related promoter element identification Zhao K,2010
We assigned a putative transcription start site to this promoter based on the observation that the majority of the σ54-dependent promoters, whose transcription start sites were determined experimentally, present a distance of 11 nucleotides between the transcription start site and the -12 box Barrios H,1999.
