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.

This protein is involved in step 1 of the subpathway that synthesizes 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route I).
Proteins known to be involved in this subpathway in this organism are:
  1. Ribose-phosphate pyrophosphokinase A (prsA), Ribose-phosphate pyrophosphokinase B (prsB), Ribose-phosphate pyrophosphokinase C (prsC)
This subpathway is part of the pathway 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis, which is itself part of Metabolic intermediate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route I), the pathway 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis and in Metabolic intermediate biosynthesis.

<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:i8EDACDFBAA680137
