RegulonDB RegulonDB 10.8: Operon Form
   

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




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


Transcription unit       
Name: aspU
Gene(s): aspU   Genome Browser M3D Gene expression COLOMBOS
Evidence: [IHBCE] Inferred by a human based on computational evidence
Promoter
Name: aspUp
+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]

Type: rho-independent
Sequence: tcccgtccgtTCCGCCACTTATTAAGAAGCCTCGAGTTAACGCTCGAGGTTTTTTTTCGTCTGTAtatctattat
Reference(s): [2] Feng CQ., et al., 2019
