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.

Component of the N-acetylglucosamine catabolic cascade that phosphorylates N-acetylglucosamine (GlcNAc), and allows the unique ability to utilise GlcNAc as carbon source. Converts GlcNAc to GlcNAc-6-P. Also able to phosphorylate glucose, glucosamine (GlcN), and mannose. Galactose, fructose, N-acetylmannosamine (ManNAc), mannosamine (ManN), galactosamine (GalN), and N-acetylgalactosamine (GalNAc) are not phosphorylated by HXK1. GlcNAc metabolism is closely associated with virulence and morphogenesis, and is involved in the cell wall synthesis. Acts both as a repressor and an activator of genes involved in maintaining cellular homeostasis. Contributes to white-opaque morphological transition and plays a role as a filamentation repressor.7 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.
