Transcription of the fis gene in CSH50 Fis protein expression is controlled by a post-transcriptional mechanism .
Transcription of the fis gene in CSH50 Fis protein expression is controlled at the level of fis transcription .
The influence of low oxygen tension on expression of the Fis protein was shown to be a manifestation of its impact on the activity of the fis gene promoter .
the fis expression in S. Typhi _ suggesting that Fis is also regulated by its level in S. enterica
