4.2.3.1
Description Threonine synthase
Alternative names Threonine synthethase;
ThrS.
Catalyzed reaction O-phospho-L-homoserine + H(2)O = L-threonine + phosphate.
Cofactor Pyridoxal-phosphate.
This enzyme participates in glycine, serine and threonine metabolism.
Threonine synthase is also a main regulatory control point of methionine synthesis in several plants, as it competes with plastidial cystathionine gamma-synthase (EC 2.5.1.48), for their common substrate O-phosphohomoserine.
