Protein attributes

Sequence length	514 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

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.
Caution	Was originally (Ref.1) thought to originate from A.thaliana.
