Pathwayi: L-ascorbate biosynthesis via UDP-alpha-D-glucuronate pathway

This protein is involved in step 4 of the subpathway that synthesizes L-ascorbate from UDP-alpha-D-glucuronate.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. no protein annotated in this organism
  3. Regucalcin (Rgn)
  4. L-gulonolactone oxidase (Gulo)
This subpathway is part of the pathway L-ascorbate biosynthesis via UDP-alpha-D-glucuronate pathway, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-ascorbate from UDP-alpha-D-glucuronate, the pathway L-ascorbate biosynthesis via UDP-alpha-D-glucuronate pathway and in Cofactor biosynthesis.
