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 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 2 of the subpathway that synthesizes myo-inositol from D-glucose 6-phosphate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Inositol-3-phosphate synthase 1 (Isyna1)
  2. Inositol-1-monophosphatase (Impa1), Inositol monophosphatase 2 (Impa2), Inositol monophosphatase 3 (Impad1), Inositol-1-monophosphatase (Impa2), Inositol monophosphatase 1 (Impa1)
This subpathway is part of the pathway myo-inositol biosynthesis, which is itself part of Polyol metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes myo-inositol from D-glucose 6-phosphate, the pathway myo-inositol biosynthesis and in Polyol metabolism.
