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