Protein

HTH-type transcriptional regulator GlnR

Gene

glnR

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score:

Annotation score:4 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the ‘correct annotation’ for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein. Note that the ‘protein existence’ evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

Transcription repressor that represses many genes including ureABC and tnrA, during nitrogen excess (PubMed:2573733, PubMed:1677938, PubMed:10231480, PubMed:18331450). On the contrary of the MerR members, which require longer DNA sites for high-affinity binding, GlnR requires a DNA sequence of 17 nucleotides as minimal binding site (PubMed:10231480, PubMed:25691471).5 Publications

Miscellaneous

The amino acid sequences of the N-terminal DNA binding domains of TnrA and GlnR are highly similar, and both proteins bind to DNA sequences with a common consensus sequence. In contrast, the C-terminal signal transduction domains of TnrA and GlnR have no homology.1 Publication

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">Function</a> section describes regulatory mechanisms for enzymes, transporters or microbial transcription factors, and reports the components which regulate (by activation or inhibition) the reaction.<p><a href='/help/activity_regulation' target='_top'>More...</a></p>Activity regulationi

Under conditions of nitrogen excess, the DNA binding activity of GlnR is activated by a transient interaction with feedback-inhibited GlnA (PubMed:18331450). Under conditions of nitrogen-limited, GlnR is autoinhibited by its C-terminal region (PubMed:25691471).2 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i5FF14F3BB2B1F1D7
