wza-wzb-wzc-wcaAB operon and associated TUs in Escherichia coli K-12 genome




Operon      
Name: wza-wzb-wzc-wcaAB
This page displays every known transcription unit of this operon and their known regulation.


Transcription unit       
Name: wzbc
Gene(s): wzc, wzb, wza   Genome Browser M3D Gene expression COLOMBOS
Note(s): The expression of this operon is increased when colicin (at 30 ng/ml) is added to the medium Kamen?ek S, ?gur-Bertok D,2013.
Evidence: [ITCR] Inferred through co-regulation
Reference(s): [1] Rhodius VA., et al., 2005
Promoter
Name: wzap2
+1: 2137193
Sigma Factor: Sigma24 Sigmulon
Distance from start of the gene: -50
Sequence: taaataaacaatgatgaaatccaaaatgaaattgatgccattattggtgtcagtaaccttGataagcggttgcacagtact
Note(s): The wza gene may have been misannotated, because the transcription start site of wzap2 is 50 bp downstream of the start site of the gene Rhodius VA,2005
