In enzymology, an UDP-glucuronate 4-epimerase (EC 5.1.3.6) is an enzyme that catalyzes the chemical reaction
Hence, this enzyme has one substrate, UDP-glucuronate, and one product, UDP-D-galacturonate.
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 UDP-glucuronate 4-epimerase. Other names in common use include uridine diphospho-D-galacturonic acid, UDP glucuronic epimerase, uridine diphosphoglucuronic epimerase, UDP-galacturonate 4-epimerase, uridine diphosphoglucuronate epimerase, and UDP-D-galacturonic acid 4-epimerase. This enzyme participates in starch and sucrose metabolism and nucleotide sugars metabolism.
Glucuronidation is often involved in drug metabolism of substances such as drugs, pollutants, bilirubin, androgens, estrogens, mineralocorticoids, glucocorticoids, fatty acid derivatives, retinoids, and bile acids. These linkages involve glycosidic bonds.
Glucuronic acid is a uronic acid that was first isolated from urine. It is found in many gums such as gum arabic, xanthan, and kombucha tea and is important for the metabolism of microorganisms, plants and animals.
Uridine 5'-diphospho-glucuronosyltransferase is a microsomal glycosyltransferase that catalyzes the transfer of the glucuronic acid component of UDP-glucuronic acid to a small hydrophobic molecule. This is a glucuronidation reaction.
Uridine diphosphate glucose is a nucleotide sugar. It is involved in glycosyltransferase reactions in metabolism.
In enzymology, a fructuronate reductase (EC 1.1.1.57) is an enzyme that catalyzes the chemical reaction
UDP-glucose 6-dehydrogenase is a cytosolic enzyme that in humans is encoded by the UGDH gene.
In enzymology, a glucuronate isomerase is an enzyme that catalyzes the chemical reaction
In enzymology, an UDP-arabinose 4-epimerase is an enzyme that catalyzes the chemical reaction
The enzyme UDP-glucose 4-epimerase, also known as UDP-galactose 4-epimerase or GALE, is a homodimeric epimerase found in bacterial, fungal, plant, and mammalian cells. This enzyme performs the final step in the Leloir pathway of galactose metabolism, catalyzing the reversible conversion of UDP-galactose to UDP-glucose. GALE tightly binds nicotinamide adenine dinucleotide (NAD+), a co-factor required for catalytic activity.
