Galactonolactone dehydrogenase (IPR010029)

Short name: GL_DH

Overlapping homologous superfamilies


Family relationships


This entry identifies L-galactono-gamma-lactone dehydrogenase EC: This enzyme performs the final step in ascorbic acid biosynthesis in higher plants. The protein is homologous to ascorbic acid biosynthesis enzymes of other species: L-gulono-gamma-lactone oxidase in rat and L-galactono-gamma-lactone oxidase in yeast. All three covalently bind the cofactor FAD.
