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>

Processive glucosyltransferase involved in the biosynthesis of both the non-bilayer-prone alpha-monoglucosyldiacylglycerol and the bilayer-forming membrane lipid alpha-diglucosyldiacylglycerol. These are major components for maintaining the anionic lipid surface charge density, for balancing the bilayer to non-bilayer phase equilibria and for keeping a constant lipid bilayer spontaneous curvature (curvature packing stress). Catalyzes the transfer of a glucosyl residue from UDP-Glc to diacylglycerol (DAG) acceptor to form the corresponding alpha-glucosyl-DAG (1,2-diacyl-3-O-(alpha-D-glucopyranosyl)-sn-glycerol), which then acts as acceptor to give alpha-diglucosyl-DAG product (3-O-(alpha-D-glucopyranosyl-alpha-(1->2)-D-glucopyranosyl)-1,2-diacyl-sn-glycerol). It can only use UDP-Glc as sugar donor.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. 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:i89D874EEF79E6793
