Reaction: GALE:NAD+ dimer reversibly epimerises UDP-Gal to UDP-Glc
- in pathway: Galactose catabolism
Cytosolic UDP-galactose 4-epimerase catalyzes the interconversion of UDP-D-galactose and UDP-D-glucose (Schulz et al. 2004). The active form of the enzyme is a homodimer with one molecule of bound NAD+ per monomer (Thoden et al. 2000).
Reaction - small molecule participants:
