Annotation score:3 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Member of the two-component regulatory system TtrR/TtrS, which is required for synthesis of tetrathionate reductase. Probably functions as a sensor protein kinase which is autophosphorylated at a histidine residue in response to tetrathionate, and transfers its phosphate group to TtrR. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut.3 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.
