Description

Threonine synthase (
4.2.3.1
) catalyses the conversion of O-phospho-L-homoserine and water into L-threonine and orthophosphate, using pyridoxal phosphate as a cofactor. The pyridoxal-phosphate binding site is a Lys (K) residue. The enzyme is distantly related to the serine/threonine dehydratases which are also pyridoxal-phosphate dependent enzymes
[1]
.

This entry represents the a group of threonine synthases from bacteria and archaea.
