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. |
