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.

Involved in the biosynthesis of the maltose-1-phosphate (M1P) building block required for alpha-glucan production by the key enzyme GlgE. Catalyzes the formation of an alpha-1,4 linkage between glucose from ADP-glucose and glucose 1-phosphate (G1P) to yield maltose-1-phosphate (M1P).1 Publication

Miscellaneous

Maltose-1-phosphate (M1P) is generated by two alternative routes: the TreS-Pep2 branch and the GlgC-GlgM branch, however it seems that the GlgC-GlgM branch provides most of M1P for the GlgE pathway in M.smegmatis.1 Publication

Cells lacking this gene do not show a discernible effect on alpha-glucan content and do not accumulate ADP-glucose. Combined inactivation of both glgM and glgB completely blocks alpha-glucan production. Combined inactivation of both glgM and ostA accumulates ADP-glucose. In the double mutant treS-glgE, inactivation of the glgM gene fully abolishes maltose 1-phosphate (M1P) production.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:iAD6F94AA26306BA2
