Transcription activation at Escherichia coli FNR-dependent promoters by the gonococcal FNR protein: effects of a novel S18F substitution and comparisons with the corresponding substitution in E. coli FNR.

The Neisseria gonorrhoeae genome encodes a homologue of the Escherichia coli FNR protein (the fumarate and nitrate reductase regulator). Despite its similarity to E. coli FNR, the gonococcal FNR only partially complemented an E.
