Sulfur-Containing Amino Acid Metabolism in Parasitic Protozoa

2005
Sulfur-containing amino acids play indispensable roles in a wide variety of biological activities including protein synthesis, methylation, and biosynthesis of polyamines and glutathione. Biosynthesis and catabolism of these amino acids need to be carefully regulated to achieve the requirement of the above-mentioned activities and also to eliminate ...

The Oxidation of Sulfur-Containing Amino Acids by L-Amino Acid Oxidases

1982
L-amino acid oxidase (LAO) from various sources is known to act on most of natural and unnatural amino acids of the L configuration (1). Among the sulfur containing amino acids, apart methionine which is known since long time as one of the best substrates for this enzyme, cystine (2), homocystine (3) and thialysine (4) have also been found more ...

Quantitative gas-liquid chromatography of sulfur containing amino acids

Journal of Chromatography A, 1968
Abstract This research describes the analytical methods for the preparation, yield, structural confirmation, RMR a.a./phen. values 2 , and substrate interaction for the volatile trimethylsilyl (TMS) derivatives of twelve sulfur amino acids: S-methyl- l -cysteine, taurine, cysteic acid, homocystine, djenkolic acid, ethionine, methionine sulfoxide and ...

The Effect of Nitrogen Deficiency and Sulfur-Containing Amino Acids on the Reduction of Sulfate to Hydrogen Sulfide by Wine Yeasts

American Journal of Enology and Viticulture, 1994
The formation of hydrogen sulfide in wine has been shown to arise from fermentations of grape musts with nitrogenous deficiencies. This work was instigated to explore this formation with the use of a qualitative, but simple, rapid, and explicit method ...

Rhenium(V) complexes with sulfur-containing amino acids

Russian Journal of Inorganic Chemistry, 2007
Rhenium(V) complexes with 2-amino-4-(methylthio)butanoic acid (methionine, Met) and 2-amino-3-sulfopropionic acid (cysteine, Cys) have been synthesized. Depending on the initial reagent ratio, the resulting complexes contain one or two ligand molecules.

Sulfur containing amino acids – challenge of accurate quantification

Journal of Analytical Atomic Spectrometry, 2012
For the first time, quantitative analysis of the proteinogenic sulfur containing amino acids methionine and cysteine was performed by LC-ICP-MS. A dedicated sample preparation procedure was implemented consisting of two steps, i.e. (1) protection of the redox sensitive amino acids by controlled oxidation of methionine, cystine and cysteine to ...

Disorders of the Sulfur-Containing Amino Acids

1990
Homocystinuria due to cystathionine-β-synthase (CBS) deficiency is the most common genetic defect of the sulfur-containing amino acids, transmitted as an autosomal recessive trait. The typical abnormalities involve the eye (ectopia lentis, myopia), the skeleton (osteoporosis, marfanoid habitus of the body, bone deformities), the central nervous system (
