Protein

Threonine synthase

Gene

thrC

Organism
Methanosarcina acetivorans (strain ATCC 35395 / DSM 2834 / JCM 12185 / C2A)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the gamma-elimination of phosphate from L-phosphohomoserine and the beta-addition of water to produce L-threonine. Does not catalyze the conversion of O-acetyl-L-homoserine into threonine.1 Publication

Catalytic activityi

O-phospho-L-homoserine + H2O = L-threonine + phosphate.1 Publication

Cofactori

pyridoxal 5'-phosphate1 Publication
