|Gene(s):||hemB 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 hemB . This structure could regulate the expression of the gene, as observed for hemL gene expression 31964733.
|Evidence:||[BTEI] Boundaries of transcription experimentally identified
[ICWHO] Inferred computationally without human oversight
|Reference(s):|| Echelard Y., et al., 1988|
|Sigma Factor:||Sigma70 Sigmulon|
|Distance from start of the gene:||27|
-35 -10 +1
|Note(s):||The -10 box of hemB (TATACT) shows a typical Pribnow box, differing only by 1 nucleotide (TATAAT). On the other hand, the -35 sequence, GTAAAA, is atypical, compared with the consensus sequence, TTGACA, for this box Echelard Y,1988. The authors suggested that mutation/deletion studies will allow better definition of its position Echelard Y,1988.|
