Transcription unit          
Name: zraP
Gene(s): zraP   Genome Browser M3D Gene expression COLOMBOS
Note(s): The transcription of zraP is induced by high concentrations of zinc |CITS:[21674266]|.
Reference(s): [1] Leonhartsberger S., et al., 2001
Promoter
Name: zraPp
+1: 4201712
Sigma Factor: Sigma54 Sigmulon
Distance from start of the gene: 24

                                  -12         -24           +1                   
Note(s): 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.
