RegulonDB RegulonDB 11.1: Operon Form

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

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

Transcription unit       
Name: menFD-yfbB-menBCE
Gene(s): menE, menC, menB, menH, menD, menF   Genome Browser M3D Gene expression COLOMBOS
Note(s): A potential RNA G-quadruplex structure, formed by guanine-rich sequences located in the coding sequence region of the gene, was identified for menF . This structure could regulate the expression of the gene, as observed for hemL gene expression Shao X, Zhang W, Umar MI, Wong HY, Seng Z, Xie Y, Zhang Y, Yang L, Kwok CK, Deng X,2020.

Transcription unit       
Name: menD-yfbB-menBCE
Gene(s): menE, menC, menB, menH, menD   Genome Browser M3D Gene expression COLOMBOS
Name: menDp
+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.
