Gene(s): yojI   Genome Browser M3D Gene expression COLOMBOS
Evidence: [ICWHO] Inferred computationally without human oversight
Promoter
Name: yojIp
+1: 2308641
Sigma Factor: Sigma70 Sigmulon
Distance from start of the gene: 26

                           -35                   -10        +1                   
Note(s): We assigned a putative transcriptional start site to this promoter based on the observation that the majority of the promoters, whose transcriptional start sites were determined experimentally, present a distance of 6 nucleotides between the transcriptional start site and the -10 box 3550697.
