Operon      
Name: rnc-era-recO-pdxJ-acpS
This page displays every known transcription unit of this operon and their known regulation.


Transcription unit       
Name: pdxJ-acpS
Gene(s): acpS, pdxJ   Genome Browser M3D Gene expression COLOMBOS
Evidence: [BTEI] Boundaries of transcription experimentally identified
[CV(LTED/PM)] cross validation(LTED/PM)
[LTED] Length of transcript experimentally determined
[PM] Polar mutation
Reference(s): [1] Matsunaga J., et al., 1996
Promoter
Name: pdxJp
+1: 2701813
Distance from start of the gene: 84
Sequence: agacacactgcgcgccgcgaaacgctttacccgcatggcgcttaagccgtatcttggcggTaaacctttaaagagcaggga

Transcription unit       
Name: rnc-era
Gene(s): era, rnc   Genome Browser M3D Gene expression COLOMBOS
Note(s): The stability of the mRNA containing rnc and era genes is negatively affected by RNAse III Matsunaga J,1996.
A potential RNA G-quadruplex structure, formed by guanine-rich sequences located in the coding sequence region of the gene, was identified for rnc. This structure could regulate the expression of the gene, as observed for hemL gene expression 31964733.
Evidence: [CV(LTED/PM)] cross validation(LTED/PM)
[LTED] Length of transcript experimentally determined
[PM] Polar mutation
