tgt-yajC-secDF operon and associated TUs in Escherichia coli K-12 genome




Operon      
Name: tgt-yajC-secDF
This page displays every known transcription unit of this operon and their known regulation.


Transcription unit       
Name: tgt-yajC
Gene(s): tgt, yajC   Genome Browser M3D Gene expression COLOMBOS
Note(s): CFNR represses yajC gene expression under anaerobiosis, but it is not known which of the two promoters transcribing the gene is affected, or even if this regulation is direct or indirect Salmon K,2003.
Evidence: [BTEI] Boundaries of transcription experimentally identified
[LTED] Length of transcript experimentally determined
Reference(s): [1] Pogliano KJ., et al., 1994
Promoter
Name: tgtp
+1: 426055
Distance from start of the gene: 82

Transcription unit       
Name: yajC-secDF
Gene(s): yajC, secD, secF   Genome Browser M3D Gene expression COLOMBOS
Note(s): The yajC gene is expressed at about 5- to 10-fold higher levels than either secD or secF.
FNR represses yajC gene expression under anaerobiosis, but it is not known which of the two promoters transcribing the gene is affected, or even if this regulation is direct or indirect Salmon K,2003.
