Sequences BBa_K1155006_sequence (Version 1)

Description

Promoter of gene nirB from E. coli. Activated by FNR in anaerobic conditions and inactivated in aerobic conditions.

The promoter of the gene narK 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(narK) 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 narK ORF and approximately 100 bp before FNR boxes
