In enzymology, an arabinose isomerase (EC 5.3.1.3) is an enzyme that catalyzes the chemical reaction

D-arabinose D-ribulose

Hence, this enzyme has one substrate, D-arabinose, and one product, D-ribulose.

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-arabinose aldose-ketose-isomerase. Other names in common use include D-arabinose(L-fucose) isomerase, D-arabinose isomerase, L-fucose isomerase, and D-arabinose ketol-isomerase.

Structural studies

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1FUI.

Ribose-5-phosphate isomerase (Rpi) encoded by the RPIA gene is an enzyme that catalyzes the conversion between ribose-5-phosphate (R5P) and ribulose-5-phosphate (Ru5P). It is a member of a larger class of isomerases which catalyze the interconversion of chemical isomers. It plays a vital role in biochemical metabolism in both the pentose phosphate pathway and the Calvin cycle. The systematic name of this enzyme class is D-ribose-5-phosphate aldose-ketose-isomerase.

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.
