RegulonDB RegulonDB 10.8: Operon Form

brnQ-proY operon and associated TUs in Escherichia coli K-12 genome

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

Transcription unit       
Name: brnQ-proY
Gene(s): brnQ, proY   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 brnQ . This structure could regulate the expression of the gene, as observed for hemL gene expression 31964733.
Evidence: [ICWHO] Inferred computationally without human oversight
