| Ec Number: | 5.1.3.22 |
In enzymology, a L-ribulose-5-phosphate 3-epimerase is an enzyme that catalyzes the chemical reaction
L-ribulose 5-phosphate
\rightleftharpoons
Hence, this enzyme has one substrate, L-ribulose 5-phosphate, and one product, L-xylulose 5-phosphate.
This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on carbohydrates and derivatives. The systematic name of this enzyme class is L-ribulose-5-phosphate 3-epimerase. Other names in common use include L-xylulose 5-phosphate 3-epimerase, UlaE, and SgaU. This enzyme participates in ascorbate and aldarate metabolism.
