Synthesis of O‐Acyl‐L‐Homoserine by lipase

Journal of the American Oil Chemists' Society, 1989
AbstractLipases (EC 3.1.1.3) fromCandida cylindracea andRhizopus delemar were found to catalyze O‐acylation of L‐homoserine or L‐serine with free fatty acids or with fatty acids from triacylglycerol. The active pH range of the reation for O‐acylation was from 7.0 to 8.5.

Engineering Corynebacterium glutamicum for efficient l-homoserine production

Bioresource Technology
l-homoserine is an important precursor in synthesizing the essential amino acids derived from l-aspartate and other valuable bio-based products, and is widely used in cosmetics, food, and pharmaceutical industries. However, the yield of l-homoserine in Corynebacterium glutamicum is limited. In this study, we successfully engineered a C.

O-Acetyl-L-homoserine: A versatile synthon for the synthesis of L-homoserine peptides and 3-amino-2-pyrrolidinones

2002
Although L-homoserine is a naturally occurring amino acid with important biological properties, only few examples of homoseryl peptides are known, which have been mainly prepared by using either the benzyl [1,2] or the trityl [3,4] group for the O-protection.

[Metabolic engineering of Escherichia coli for L-homoserine production].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2021
L-Homoserine is a non-essential amino acid that is often used as an important platform compound and additive in industrial production. To improve the production efficiency, a previously constructed L-homoserine producing strain E. coli H0-0 was used as a chassis for further metabolic modification.

Preparation of d-, dl-, and l-homoserine lactone from methionine

Microchemical Journal, 1989
Abstract A practical procedure is described for the replacement of the methylmercapto group of the readily available d - and l -methionine with an hydroxyl group, thus forming the d and l forms of homoserine, in a high degree of purity. Yields were in excess of 75%.

Roles of O-acetyl-l-homoserine sulfhydrylases in microorganisms

Biochimie, 1989
O-Acetyl-L-homoserine sulfhydrylase (EC 4.2.99.10) is essential for certain micro-organisms, functioning as a homocysteine synthase in the pathway of methionine synthesis. It participates in an alternative pathway of L-homocysteine synthesis for those microbes in which homocysteine is synthesized mainly via cystathionine.

Improved procedure for synthesis of radioactive O-succinyl-l-homoserine

Analytical Biochemistry, 1977
Abstract A method for the small scale synthesis of O -succinyl- l -homoserine, which is well suited for the preparation of radioactive material, is described. The procedure consists of three steps (t-butoxycarbonylation of the amino group, succinylation of the N -t-butoxycarbonyl (BOC) homoserine, and removal of the t-butoxycarbonyl group) all of ...

Accumulation of O-methyl-L-homoserine by methanol-utilizing bacteria

Biotechnology Letters, 1980
Several classes of mutants derived from facultative methylotrophs, Microcyclus eburneus and Protaminobacter ruber, accumulate 0.5–3.8 mg/ml of O-methyl-L-homoserine (OMH) in a medium containing methanol as sole carbon source. The wild-type parent strains also accumulate OMH when the medium is supplemented with L-homoserine; the accumulation of OMH by ...
