Threonine synthase
Definition:
EC Tree > 4 Lyases > 4.2 Carbon-oxygen lyases > 4.2.3 Acting on phosphates > 4.2.3.1 threonine synthase
Threonine synthase is a pyridoxal-phosphate-dependent gamma-elimination/replacement enzyme. It cleaves O-phospho-L-homoserine with water, replacing the phosphate with hydroxyl, into L-threonine and phosphate, the final step of threonine biosynthesis from aspartate. It is found in Bacteria, Eukaryota and Archaea. Structurally it is a PLP-dependent fold-II threonine synthase.
