In enzymology, a glucuronate isomerase (EC 5.3.1.12) is an enzyme that catalyzes the chemical reaction

D-glucuronate D-fructuronate

Hence, this enzyme has one substrate, D-glucuronate, and one product, D-fructuronate.

This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases interconverting aldoses and ketoses. The systematic name of this enzyme class is D-glucuronate aldose-ketose-isomerase. Other names in common use include uronic isomerase, uronate isomerase, D-glucuronate isomerase, uronic acid isomerase, and D-glucuronate ketol-isomerase. This enzyme participates in pentose and glucuronate interconversions.

Structural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1J5S and 2Q01.

<span class="mw-page-title-main">Xylose isomerase</span> Class of enzymes

In enzymology, a xylose isomerase is an enzyme that catalyzes the interconversion of D-xylose and D-xylulose. This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases interconverting aldoses and ketoses. The isomerase has now been observed in nearly a hundred species of bacteria. Xylose-isomerases are also commonly called fructose-isomerases due to their ability to interconvert glucose and fructose. The systematic name of this enzyme class is D-xylose aldose-ketose-isomerase. Other names in common use include D-xylose isomerase, D-xylose ketoisomerase, and D-xylose ketol-isomerase.
