This protein is involved in step 5 of the subpathway that synthesizes L-threonine from L-aspartate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Aspartokinase (HOM3)
  2. Aspartate-semialdehyde dehydrogenase (HOM2)
  3. Homoserine dehydrogenase (HOM6)
  4. Homoserine kinase (THR1)
  5. Threonine synthase (THR4)
This subpathway is part of the pathway L-threonine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-threonine from L-aspartate, the pathway L-threonine biosynthesis and in Amino-acid biosynthesis.
