1.1.1.203 | evolution |
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 |

1.1.1.203 | 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 |
