General Information
the enzyme belongs to the short-chain dehydrogenase/reductase (SDR) superfamily
UDH is a member of the short-chain dehydrogenase/reductase(SDR) superfamily, whose members typically contain a single domain having a highly variable C-terminal substrate binding site, reflecting the diverse nature of SDR substrates and attendant substrate binding site structures, and a conserved N-terminal cofactor binding site
the enzyme is proposed to be part of the salvage pathway in ascorbate production as galacturonate acid reductase, GalUR, EC, converting D-galacturonate to L-galactono-1,4-lactone, ascorbate biosynthesis and recycling pathways in plants, overview
uronate dehydrogenases catalyse the initial step in an oxidative pathway
uronate dehydrogenases catalyses the initial step in an oxidative pathway
physiological function
ascorbate accumulation is affected mainly by biosynthesis rather than recycling in radish root, and the L-galactose pathway may be the major biosynthetic route of ascorbate, and moreover, the salvage pathway may also contribute to ascorbate accumulation. Ascorbate level regulation involves the D-galacturonate reductase and GDP-D-mannose diphosphorylase
