    Pathwayi: UDP-alpha-D-glucuronate biosynthesis

    This protein is involved in step 1 of the subpathway that synthesizes UDP-alpha-D-glucuronate from UDP-alpha-D-glucose.
    Proteins known to be involved in this subpathway in this organism are:
    1. UDP-glucose 6-dehydrogenase 2 (UGD2), UDP-glucose 6-dehydrogenase 1 (UGD1), UDP-glucose 6-dehydrogenase 4 (UGD4), UDP-glucose 6-dehydrogenase 3 (UGD3)
    This subpathway is part of the pathway UDP-alpha-D-glucuronate biosynthesis, which is itself part of Nucleotide-sugar biosynthesis.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes UDP-alpha-D-glucuronate from UDP-alpha-D-glucose, the pathway UDP-alpha-D-glucuronate biosynthesis and in Nucleotide-sugar biosynthesis.
