Enzyme reactions

• Enzyme class: E.C.4.2.3.1 - threonine synthase.
• Pathway: Threonine Biosynthesis
• Reaction: O-phospho-L-homoserine + H2O = L-threonine + phosphate

O-phospho-L-homoserine + H2O = L-threonine (Bound ligand (Het Group name = KPA) matches with 42.86% similarity) + phosphate

• Cofactor: Pyridoxal 5'-phosphate
