"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… " - Phosphohomoserine

WebWhat is the first reaction step after the phosphohomoserine links to PLP? abstraction of a proton at the α carbon There are two routes for transforming aspartate to asparagine at the expense of ATP. Many bacteria have an asparagine synthetase that uses ammonium ion as the nitrogen donor. 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.

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 … 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.
