folX-yfcH operon and associated TUs in Escherichia coli K-12 genome

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

Transcription unit       
Name: folX-yfcH
Gene(s): folX, yfcH   Genome Browser M3D Gene expression COLOMBOS
Evidence: [BTEI] Boundaries of transcription experimentally identified
[ICWHO] Inferred computationally without human oversight
Reference(s): [1] Zaslaver A., et al., 2006
Name: folXp
+1: Unknown
Note(s): Zaslaver et al. demonstrated in 2006, by means of a library of fluorescent transcription fusions, that this promoter can be transcribed in vitro Zaslaver A,2006. Based on this, a putative promoter was suggested, but the +1 site of the transcription initiation has not been determined, although there exists promoter activity.
