In enzymology, a L-rhamnose isomerase (EC 5.3.1.14) is an enzyme that catalyzes the chemical reaction

L-rhamnose L-rhamnulose

Hence, this enzyme has one substrate, L-rhamnose, and one product, L-rhamnulose.

This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases interconverting aldoses and ketoses. The systematic name of this enzyme class is L-rhamnose aldose-ketose-isomerase. Other names in common use include rhamnose isomerase, and L-rhamnose ketol-isomerase. This enzyme participates in fructose and mannose metabolism.

Structural studies

As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1D8W, 1DE5, 1DE6, 2HCV, 2I56, and 2I57.

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.
