General annotation (Comments)

Function

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

Catalytic activity

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

Cofactor

Pyridoxal phosphate By similarity.

Pathway

Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine from L-aspartate: step 5/5.

Sequence similarities

Belongs to the threonine synthase family.
