RegulonDB RegulonDB 10.9: Operon Form
   

yjjB-dnaTC-yjjA operon and associated TUs in Escherichia coli K-12 genome




Operon      
Name: yjjB-dnaTC-yjjA
This page displays every known transcription unit of this operon and their known regulation.


Transcription unit       
Name: dnaTC-yjjA
Gene(s): yjjA, dnaC, dnaT   Genome Browser M3D Gene expression COLOMBOS
Note(s): The yjjA terminator is preceded by a sequence that matches well with the boxA sequence 6218883. This sequence could be recognized by the host NusA protein that is associated with both rho-dependent and -independent termination signals Masai H,1988.
Evidence: [BTEI] Boundaries of transcription experimentally identified
[ITCR] Inferred through co-regulation
[LTED] Length of transcript experimentally determined
Reference(s): [1] Masai H., et al., 1988
Promoter
Name: dnaTp
+1: 4601615
Distance from start of the gene: 98
Sequence: cggtctttccattcctggattatggttgtaccgcaagcgccctcgcgtataaaattgcctCgcttaagcacacggatgaga
Note(s): The expression controlled by dnaTp can terminate at both terminators (t1 and t2) located downstream of the dnaC and yjjA genes, respectively. Transcription from dnaTp is stronger than from yjjBp Masai H,1988
Evidence: [HIPP]

Distance from start of the gene: 80

Note(s): Even though of yjjBp was determined by Northern blotting, it was not shown in the sequences presented by Masai H,1988. However, they mentioned that it could be present at 660 bp upstream of the dnaT gene. The expression controlled by yjjBp can terminate at both terminators (t1 and t2) located downstream of the dnaC and yjjA genes, respectively. Transcription from yjjBp is weak compared to that from dnaTp and therefore its contribution to dnaT/dnaC expression is not significant Masai H,1988.
