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>

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants, fungi and bacteria.

<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. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori

Protein has several cofactor binding sites:

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">'Function'</a> section describes the metabolic pathway(s) associated with a protein.<p><a href='/help/pathway' target='_top'>More...</a></p>Pathwayi: nitrate reduction (denitrification)

This protein is involved in step 1 of the subpathway that synthesizes dinitrogen from nitrate.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Assimilatory nitrate reductase catalytic subunit (nasC)
  2. no protein annotated in this organism
  3. no protein annotated in this organism
  4. no protein annotated in this organism
This subpathway is part of the pathway nitrate reduction (denitrification), which is itself part of Nitrogen metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes dinitrogen from nitrate, the pathway nitrate reduction (denitrification) and in Nitrogen 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.
