Annotation score:4 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>
-Protein inferred from homologyi <p>This indicates the type of evidence that supports the existence of the protein. Note that the ‘protein existence’ evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

<p>This subsection of the ‘Function’ section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states.

This protein is involved in step 1 of the subpathway that synthesizes quinolinate from L-kynurenine.UniRule annotation
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Kynurenine 3-monooxygenase (kmo-1)
  2. Kynureninase (flu-2)
  3. 3-hydroxyanthranilate 3,4-dioxygenase (haao-1)
This subpathway is part of the pathway NAD(+) biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes quinolinate from L-kynurenine, the pathway NAD(+) biosynthesis and in Cofactor 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.
