Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Triosephosphate isomerase is an extremely efficient metabolic enzyme that catalyzes the interconversion between dihydroxyacetone phosphate (DHAP) and D-glyceraldehyde-3-phosphate (G3P) in glycolysis and gluconeogenesis.By similarity
It is also responsible for the non-negligible production of methylglyoxal a reactive cytotoxic side-product that modifies and can alter proteins, DNA and lipids.By similarity

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">Function</a> section describes the catalytic activity of an enzyme, i.e. a chemical reaction that the enzyme catalyzes.<p><a href='/help/catalytic_activity' target='_top'>More...</a></p>Catalytic activityi

View all proteins of this organism that are known to be involved in the pathway gluconeogenesis and in Carbohydrate biosynthesis.

Pathwayi: glycolysis

This protein is involved in step 1 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate from glycerone phosphate.PROSITE-ProRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Triosephosphate isomerase (tpi-1)
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
