WebDec 11, 2001 · 1KL7. PubMed Abstract: Threonine synthase catalyzes the final step of threonine biosynthesis, the pyridoxal 5'-phosphate (PLP)-dependent conversion of O-phosphohomoserine into threonine and inorganic phosphate. Threonine is an essential nutrient for mammals, and its biosynthetic machinery is restricted to bacteria, plants, and … WebFurther, international patent application publication WO2014/064244 discloses a method for producing methionine from O-phosphohomoserine by using sulfide and invertase. On this basis, it was confirmed that phosphate is essential as a phosphorus source for producing O-phosphohomoserine by fermentation, which is a precursor of methionine.
