Catalytic Mechanism of Fungal Homoserine Transacetylase
Biochemistry, 2005Homoserine 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.

Optical enantiomorphs of homoserine and homocystine
Archives of Biochemistry and Biophysics, 1953Abstract Chloroacetyl- dl -homoserine lactone was synthesized. After opening the ring at pH 8, and treating with hog kidney acylase I, dl -homoserine ([α]D = −8.8 ° in water and +18.3 ° in 2 N HCl) was obtained in 72% yield. From the mother liquor, chloroacetyl- d -homoserine was separated, yielding on HCl hydrolysis the lactone of d -homoserine ...

New homoserine lipids from Xerocomus langbianensis
Journal of Basic Microbiology, 2002New diacylglycerotrimethyl homoserine lipids 1 (2 O,3 O-bislinolylglycero-4'-O-(N,N,N-trimethyl)homoserine) and 2 (2 O,3 O-linolyl-palmitylglycero-4'-O-(N,N,N-trimethyl)-homoserine) were isolated from the fruiting body of a Vietnamese species of Xerocomus langbianensis.

[195g] Homoserine transacetylase (Neurospora)
1971Publisher 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

Synthesis of some homoserine derivatives
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19671. 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.

Independent folding regions in aspartokinase-homoserine dehydrogenase
Biochemistry, 1981The folding of two monofunctional fragments of aspartokinase-homoserine dehydrogenase I has been studied. One of these fragments corresponds to the kinase activity and the N-terminal part of the polypeptide chain; the other one corresponds to the dehydrogenase activity and to the C-terminal part of the chain.

Homoserine kinase from barley seedlings
Plant Science Letters, 1976Abstract Homoserine kinase was partially purified from 4-day-old etiolated barley seedlings (Hordeum vulgare L.). The enzyme activity required the presence of divalent ions (Mg2+ > Mn2+ > Zn2+ > Co2+). Monovalent cations (K+ or NH4+) were also required for catalytic activity. Homoserine and MgATP protected the enzyme against heat inactivation.

Biosynthesis of Homoserine Lipid
19891,2-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).
