RegulonDB RegulonDB 11.1: Operon Form

umpG-pcm operon and associated TUs in Escherichia coli K-12 genome

Name: umpG-pcm
This page displays every known transcription unit of this operon and their known regulation.

Transcription unit       
Name: umpG-pcm
Synonym(s): surE-pcm
Gene(s): pcm, umpG   Genome Browser M3D Gene expression COLOMBOS
Note(s): Based on fusions with lacZ, a promoter (designated P3) was identified upstream of the pcm gene. It was induced both in growing cells and in cells approaching stationary phase, both independent of σS. However, any good promoter could be identified in this region by sequence comparison. Primer extension analysis was not done for identifying the +1 site of the transcriptional start site Li C, Wu PY, Hsieh M,1997
Evidence: [EXP-IMP-POLAR-MUTATION] Polar mutation
[IC-ADJ-GENES-SAME-BIO-PROCESS] Products of adjacent genes in the same biological process

Name: surEp2
+1: 2870686
Sigma Factor: Sigma70 Sigmulon
Distance from start of the gene: 412

                              -35                        -10+1                   
Note(s): Although surEp2 is expressed in the stationary phase, it is not controlled by the rpoS sigma factor. surEp2 presents a typical σ70 promoter with homologous -10 and 35 regions Li C, Wu PY, Hsieh M,1997
