Promoter of nirB, activated by FNR in anaerobic conditions
| Types | DnaRegion |
| Roles | promoter Regulatory |
| Sequences | BBa_K1155004_sequence (Version 1) |
Description
Promoter of gene nirB from E. coli. Ectivated by FNR in anaerobic conditions and inactivated in aerobic conditions.The promoter of the gene nirB is regulated by FNR. It's a class II promoter with two FNR boxes. (Scott et al, FEBS letter, 2003)
Aerobic conditions: +O2 --> FNR inactivated --> Promoter non activated
Anaerobic conditions: - O2 --> FNR activated --> Promoter activated
P(nirB) is predicted to be highly induced under anaerobic conditions :48-64 fold. (Lolesnikow et al, J. bacteriol 1992 / Griffiths et al, Arch. Microbiol. 1987 / Green et al, Mol. Microbiol, 1998)
Notes
We conserved all the promoter region until the last nucleotide before nirB ORF and approximately 100 bp before FNR boxesSource
