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>
-Protein inferred from homologyi <p>This indicates the type of evidence that supports the existence of the protein.

<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

This protein is involved in step 1 of the subpathway that synthesizes L-glutamate from 2-oxoglutarate and L-glutamine (ferredoxin route).
Proteins known to be involved in this subpathway in this organism are:
  1. Ferredoxin-dependent glutamate synthase (gltB)
This subpathway is part of the pathway L-glutamate biosynthesis via GLT pathway, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-glutamate from 2-oxoglutarate and L-glutamine (ferredoxin route), the pathway L-glutamate biosynthesis via GLT pathway and in Amino-acid biosynthesis.

Pathwayi: nitrogen metabolism

This protein is involved in the pathway nitrogen metabolism, which is part of Energy metabolism.
