Increasing L-homoserine production in Escherichia coli by engineering the central metabolic pathways

Journal of Biotechnology, 2020
l-homoserine is an important functional amino acid. Based on the system metabolic engineering strategy, the key genes in the central metabolic pathway of Escherichia coli W3110 were engineered to construct the strain for l-homoserine production. To construct an engineered strain with high yield of l-homoserine, the work was carried out from the ...

Enzymatic synthesis of l-cystathionine from the succinic ester of l-homoserine

Biochimica et Biophysica Acta (BBA) - General Subjects, 1965
Abstract The product of the reaction between l -cysteine and O- succinyl - l - homoserine , catalyzed by an enzyme from Salmonella, has been shown to be l -cystathionine. The three times recrystallized reaction product and authentic l -cystathionine have identical infrared spectra and optical-rotary dispersion curves, are decomposed at ...

Improved Synthesis of L-Homoserine Derivatives from L-Aspartic Acid

Synthesis, 1991
N-Alkoxycarbonyl-L-homoserine lactones (α-alkoxycarbonyl-amino- γ-butyrolactones) were prepared by selective esterification of L-aspartic acid followed by N-protection, precipitation of the dicyclohexylammonium salts, chemoselective reduction with lithium borohydride, and cyclization to the corresponding γ-lactones during ...

O-Aacetyl-l-serine-O-acetyl-l-homoserine sulfhydrylase from Saccharomyces cerevisiae

1987
Publisher Summary The physiological function of O-acetylserine-O-acetylhomoserine sulfhydrylase of Saccharomyces cerevisiae is the biosynthesis of both cysteine and homocysteine. The products of these reactions, cysteine and homocysteine, are determined after removing sulfide at an acidic pH by reaction with nitroprusside.
