How can you use “fnr” in a sentence? Here are some example sentences to help you improve your vocabulary:

Also, both half-sites of the Fnr recognition sequence at dmsA are required for Fnr-dependent expression and are similar in their ability to activate dmsA transcription.
In this study, the control of dmsABC gene expression by Fnr and NarL was investigated.
These studies define the molecular interactions of Fnr and NarL at the dmsABC P1 promoter that together provide for the oxygen and nitrate regulated expression of this respiratory pathway operon.
The 114-fold anaerobic activation seen for the wild-type dmsA promoter was reduced to about 35-fold in each of the two mutants (Figure 1), indicating that the position of the Fnr site at the wild-type dmsA promoter is important for controlling optimal dmsA gene expression.
The enhanced ability of Fnr to activate dmsABC gene expression is possibly, by analogy to Crp, due to increased affinity of Fnr at the consensus versus the native non-consensus Fnr recognition sequence at dmsA . Likewise, the poor match of the Fnr site at the promoter for the fumarate reductase gene, frdA to the consensus Fnr sequence may account for the relatively weak anaerobic induction for this respiratory operon [ 14 ] .
