General Information | Comment | Organism |
---|---|---|
metabolism | enzyme D-galacturonic acid reductase, GalUR, is involved in the D-galacturonic acid pathway for ascorbic acid biosynthesis | Rosa roxburghii |
physiological function | L-ascorbic acid and L-ascorbic acid pool size accumulation in the leaves of Rosa roxburghii are regulated by both biosynthesis and recycling, and enzyme D-galacturonic acid reductase, GalUR, in the D-galacturonic acid pathway and monodehydroascorbate reductase, MDHAR, in the recycling pathway play important roles in this process | Rosa roxburghii |
