Example sentences for: narl

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

To evaluate where NarL binds, DNase I footprinting experiments were performed using a dmsA promoter fragment corresponding to -127 to + 62 relative to the start of transcription at P1.
Furthermore, the spacing between the Fnr and RNA polymerase recognition sequences is critical at dmsA . In vitro interactions of the nitrate-responsive regulatory protein NarL with the promoter region of dmsABC were examined using DNase I and hydroxyl radical footprinting techniques.
Furthermore, non-phosphorylated NarL gave no DNase I protections in the dmsA promoter region under the same conditions for either strand (up to 10 μM), suggesting that NarL-phosphate, but not NarL, can act as a transcriptional repressor for dmsA expression.
Location of NarL binding sites at the dmsApromoter
However, a somewhat weaker binding of NarL-phosphate to the DNA fragment containing the truncated dmsA region relative to the full-length region may suggest that NarL binds at the promoter in a weakly cooperative fashion.
