WebA short efficient synthesis of the threonine synthase substrate (2)--phosphohomoserine and its C-2 deuteriated and C-3 chirally deuteriated isotopomers is described. The synthetic … WebApr 1, 2002 · The magnitude of TS affinity for O-phosphohomoserine also appears to be highly regulated. In vitro biochemical studies showed that the TS affinity for O-phosphohomoserine is stimulated by SAM, an immediate product of methionine 13., 16.. This suggests that methionine regulates its own synthesis through SAM.
Homoserine (also called isothreonine) is an α-amino acid with the chemical formula HO2CCH(NH2)CH2CH2OH. l-Homoserine is not one of the common amino acids encoded by DNA. It differs from the proteinogenic amino acid serine by insertion of an additional -CH2- unit into the backbone. Homoserine, or its lactone form, is the product of a cyanogen bromide cleavage of a peptide by degr… WebEstimates of kinetic constants for the three enzyme activities indicate that O-acetylserine sulfhydrylase has much higher activity and affinity for sulfide than O-phosphohomoserine …
WebInorganic phosphate is released from phosphohomoserine. Although apparently simple, the reaction is actually quite complex: (vi) Isoleucine: Isoleucine is an isomer of leucine, but the two amino acids are synthesized by different pathways. It can be seen from Fig. 8.74 that isoleucine is synthesized from threonine.

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.
