Transcription unit       
Name: radD
Gene(s): radD   Genome Browser M3D Gene expression COLOMBOS
Evidence: [ICWHO] Inferred computationally without human oversight
Promoter
Name: radDp
+1: 2280622
Sigma Factor: Sigma54 Sigmulon
Distance from start of the gene: 10
Sequence: ctaataacatccctcaagggaaaaagatccatggcatactattagcagaataatctacctAcgcgagaccatgatttttac
                                -24         -12             +1                   
Note(s): This promoter was identified by microarray 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.
