L-arabinose isomerase

From Wikipedia, the free encyclopedia

In enzymology, a L-arabinose isomerase (EC 5.3.1.4) is an enzyme that catalyzes the chemical reaction

L-arabinose L-ribulose

Hence, this enzyme has one substrate, L-arabinose, and one product, L-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 L-arabinose aldose-ketose-isomerase. This enzyme participates in pentose and glucuronate interconversions.
