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.

Miscellaneous

GK1 has a half-life of 92 minutes while GK2 has a half-life of 11 minutes at 49 degrees Celsius.

Caution

E.coli has 2 glycerate kinases, GK1 and GK2; it is not clear which gene encodes which enzyme. PubMed:5325263 may be a mix of GK1 and GK2.Curated

    This protein is involved in step 4 of the subpathway that synthesizes 3-phospho-D-glycerate from glycolate.
    Proteins known to be involved in the 4 steps of the subpathway in this organism are:
    1. no protein annotated in this organism
    2. Glyoxylate carboligase (gcl)
    3. 2-hydroxy-3-oxopropionate reductase (glxR)
    4. Glycerate 3-kinase (glxK)
    This subpathway is part of the pathway glycolate degradation, which is itself part of Organic acid metabolism.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes 3-phospho-D-glycerate from glycolate, the pathway glycolate degradation and in Organic acid metabolism.

    <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:i0F902DF27DE63578
