UDP-glucose 4-epimerase

UDP-glucose 4-epimerase
UDP-glu·cose 4-epim·er·ase (glooґkōs ə-pimґər-ās) [EC 5.1.3.2] an enzyme of the isomerase class that catalyzes the interconversion of UDP-galactose and UDP-glucose in the metabolism of galactose, requiring NAD+ as a cofactor. Deficiency of the enzyme in erythrocytes, an autosomal recessive trait, causes accumulation in red cells of galactose 1-phosphate. Called also UDP-galactose 4-epimerase.
