RegulonDB RegulonDB 10.10: Operon Form

yjfKLMC operon and associated TUs in Escherichia coli K-12 genome

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

Transcription unit       
Name: yjfKLMC
Gene(s): yjfK, yjfL, yjfM, yjfC   Genome Browser M3D Gene expression COLOMBOS
Evidence: [ICWHO] Inferred computationally without human oversight
Name: yjfKp
+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.
Evidence: [IEP]
