Annotation score:3 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.

A D-serine-specific transporter, may function as a H+ symporter.By similarity

Caution

An ORF called dsdC was originally (PubMed:3275618) assigned to the wrong DNA strand and thought to be a D-serine deaminase activator, it was then resequenced by Ref. 2 and still thought to be 'dsdC', but this time to function as a D-serine permease. It is PubMed:7592420 that showed that dsdC is another gene and that this sequence should be called dsdX. It should also be noted that the C-terminal part of dsdX (from 338 onward) was also sequenced (PubMed:3029015 and PubMed:1659648) and was thought to be a separate ORF (don't worry, we also had difficulties understanding what happened!).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:iF88D821090A3F79F
