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>

Cleaves the beta-1,4-linkages between beta-D-galactose and alpha-L-3,6-anhydro-galactose residues in agarose. Cleaves agarose in a random manner with retention of the anomeric-bond configuration, producing beta-anomers that give rise progressively to alpha-anomers when mutarotation takes place.1 Publication

Miscellaneous

Gut bacteria supply the human body with energy from dietary polysaccharides through glycosidases that are absent in the human genome. Beta-agarases, which are active on agarose from marine red algae of the genus Porphyra, are present in marine bacteria. They are absent from metagenome data of gut bacteria, except from the genome of the gut bacterium B.plebeius isolated from Japanese individuals. Seaweeds make an important contribution to the diet in Japan and Porphyra (nori) is the most important nutritional seaweed used to prepare sushi, suggesting that seaweeds with associated marine bacteria have been the route by which genes coding for beta-agarases have been transferred in human gut B.plebeius genome (PubMed:20376150 and PubMed:23150581).

<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:i390E5D966B4018F2
