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.

Is probably involved in the catabolism of alpha-glycosides accumulated via a phosphoenolpyruvate-dependent phosphotransferase system (PEP-PTS). Hydrolyzes a wide variety of 6-phospho-alpha-D-glucosides including the five isomeric derivatives of sucrose, i.e. trehalulose-6'-phosphate, turanose-6'-phosphate, maltulose-6'-phosphate, leucrose-6'-phosphate, and palatinose-6'-phosphate, but is not active on sucrose-6-phosphate. Can also hydrolyze maltose-6'-phosphate and methyl-alpha-glucose-6-phosphate, and poorly, trehalose-6-phosphate. Fails to hydrolyze beta-O-linked phosphorylated disaccharides such as cellobiose-6'-phosphate and gentiobiose-6'-phosphate. Does not seem to be involved in maltose catabolism.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.
