Annotation score:5 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>

Plays an essential role in generating the deoxyribonucleotide precursors dATP AND dCTP for DNA metabolism. The phosphate acceptor specificity is strict toward deoxyadenosine (dAdo) and deoxycytidine (dCyd). The specificity toward the sugar moiety of the nucleoside is less strict. Both 2-deoxyribose, ribose, and arabinose nucleosides are phosphorylated, although the 2-deoxyribonucleosides are preferred. The phosphate donor specificity is dependent on the deoxyribonucleoside substrate, but GTP is efficient with both deoxycytidine and deoxyadenosine. Only nucleoside triphosphates can act as phosphate donors.1 Publication

Deoxyadenosine inhibits deoxycytidine phosphorylation and deoxycytidine inhibits deoxyadenosine phosphorylation. Deoxyadenosine/deoxycytidine kinase is inhibited by both dATP and dCTP.1 Publication

    <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:iB02CDBAA1C518305
