Transcription unit       
Name: rimK-ybjN
Gene(s): rimK, ybjN   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 rimK . 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.
