Phosphohomoserine

WebThe biosynthesis pathways of the essential amino acids methionine and threonine diverge from O-phosphohomoserine, an intermediate metabolite in the aspartate family of amino acids. Thus, the enzymes cystathionine-γ-synthase (CGS) in the methionine pathway and threonine synthase (TS), the last enzyme in the threonine pathway, compete for this … 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 …

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.

WebParallel studies of O-phosphohomoserine sulfhydrylase and O-acetylserine sulfhydrylase showed that O-phosphohomoserine sulfhydrylase activity responded to growth conditions identically to cystathionine gamma-synthase activity, whereas O-acetylserine sulfhydrylase activity remained unaffected. 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…
