Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the gamma-elimination of phosphate from L-phosphohomoserine and the beta-addition of water to produce L-threonine.By similarity

Catalytic activityi

O-phospho-L-homoserine + H2O = L-threonine + phosphate.

Cofactori

Pathway: L-threonine biosynthesis

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. Probable aspartokinase (MJ0571)
  2. Aspartate-semialdehyde dehydrogenase (asd)
  3. Homoserine dehydrogenase (hom)
  4. Homoserine kinase (thrB)
  5. Threonine synthase (thrC)
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.
