Synthesis of some homoserine derivatives [PDF]

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1967
1. Some new homoserine derivatives, substituted on the hydroxy, amino and carboxyl groups, were obtained. 2. The N-phosphorylation of homoserine cyclohexylamide was accomplished using O-phenyl-N-bis(β-chloroethyl) phosphoramidic chloride.

Catalytic Mechanism of Fungal Homoserine Transacetylase

Biochemistry, 2005
Homoserine transacetylase is a required catalyst in the biochemical pathway that metabolizes Asp to Met in fungi. The enzyme from the yeast Schizosaccharomyces pombe activates the hydroxyl group of L-homoserine by acetylation from acetyl coenzyme A. This enzyme is unique to fungi and some bacteria and presents an important new target for drug discovery.

Properties of homoserine dehydrogenase in a thermophilic bacterium

Biochimica et Biophysica Acta (BBA) - Enzymology, 1973
Abstract A highly thermostable homoserine dehydrogenase ( l -homoserine NADP+-oxidoreductase, EC 1.1.1.3) from a thermophilic organism is described. Maximal activity was obtained to 70†C and at a pH of 9.8; K+-was essential for activity. The enzyme was feedback inhibited by l -threonine, the inhibition being of a competitive type.

Homoserine inhibition of in vitro sickling of erythrocytes

Experimental and Molecular Pathology, 1975
Abstract Homoserine blocks and reverses significantly the sickling of sickle cell erythrocytes in vitro at 0.05–0.1 M concentrations and delays the gel formation of hemoglobin S at 37°C. The effect of homoserine on the inhibition of erythrocyte sickling is reversible when the cell suspension is diluted extensively with buffer before deoxygenation.

Biosynthesis of Homoserine Lipid

1989
1,2-Diacylglyceryl-O-4’-(N,N,N-trimethyl)homoserine (DGTS) is a glycerolipid which is widely distributed in lower green plants (pteridophytes, bryophytes, and chlorophytes) and some chromophytes (Brown and Elovson 1974, Eichenberger 1982, Sato and Furuya 1984, 1985).

Homoserine dehydrogenases of Serratia marcescens Sa-3

Biochemical and Biophysical Research Communications, 1971
Abstract (i) At least two methionine-repressible H s DH s are present in S. marcescens S a -5 and these account for the most (90%) of the H s DH activity, (ii) the NAD + -activity is completely, and the NADP + -H s DH strongly (75–80%) repressed by L-methionine, L-cysteine and L-homoserine, but both seem to be sensitive only to cysteine among ...

[195g] Homoserine transacetylase (Neurospora)

1971
Publisher Summary This chapter discusses the methods of preparation of Homoserine Transacetylase ( Neurospora ). O -Acetylhomoserine is converted by mild alkaline treatment to N-acetylhomoserine. Starting with radioactive homoserine the resulting radioactive N-acetylhomoserine can readily be separated as it is not retained by Dowex 50-H. This method
