Biological response of Schiff base metal complexes incorporating amino acids – a short review
Journal of coordination chemistry, 2020Metal complexes have more biological activities than their corresponding ligands. In particular, Schiff base complexes are of great interest due to their stability, electron donating ability, catalytic, photochromic, optical nonlinearity properties and ...

Disorders of Sulfur Amino Acid Metabolism
2000Several inherited defects are known in the conversion of the sulfur-containing amino acid methionine to cys teine and the ultimate oxidation of cysteine to inorganic sulfate (Fig. 21.1). Cystathionine β-synthase (CBS) deficiency is the most important.

A new sulfur-containing amino acid
Archives of Biochemistry and Biophysics, 1961Abstract A new acidic amino acid (C8H15O4NS) containing cysteine residue was isolated from the urine of an atherosclerotic patient. It melted at 213 ° with decomposition. Crystalline form is rhombic plate from 50% alcohol. Ninhydrin color is blue on paper chromatogram. Rf values are 0.58-0.65 in butanol-acetic acid-water and 0.43-0.53 in phenol-water.

Biotechnology Advances
L-Cysteine and L-methionine, as the only two sulfur-containing amino acids among the canonical 20 amino acids, possess distinct characteristics and find wide-ranging industrial applications. The use of different organisms for fermentative production of L-

Several sulfur amino acids and sulfur compounds are found in mammalian tissues. While some find their origin in the diet, other sulfur amino acids are formed in vivo from methionine in the tissues. Thus it is known that methionine is converted into homocysteine, cystathionine, cysteine, hypotaurine, and taurine.

Metabolism of Sulfur-Containing Amino Acids
Annual Review of Nutrition, 1986Met metabolism occurs primarily by activation of Met to AdoMet and further metabolism of AdoMet by either the transmethylation-transsulfuration pathway or the polyamine biosynthetic pathway. The catabolism of the methyl group and sulfur atom of Met ultimately appears to be dependent upon the transmethylation-transsulfuration pathway because the MTA ...

Peroxymonosulfate Oxidizes Amino Acids in Water without Activation.
Environmental Science and Technology, 2019A variety of peptidic and proteinaceous contaminants (e.g., proteins, toxins, pathogens) present in the environment may pose risk to human health and wildlife.

Requirement for Sulfur-Containing Amino Acids in Infancy
The Journal of Nutrition, 1986A series of studies designed to define the requirement of normal infants for sulfur-containing amino acids (methionine, cystine) was conducted with formulas providing 3.0, 2.8, 2.6, 2.2 or 1.8 g of isolated soy protein per 100 kcal. The formulas were fed with or without a methionine supplement.

BIOCHEMISTRY OF SULFUR-CONTAINING AMINO ACIDS
Annual Review of Biochemistry, 1983The literature on sulfur amino acid metabolism is too vast for a short chapter to cover in great depth. I attempt here a brief overview with references to many specialized review articles. This review emphasizes aspects of sulfur amino acid metabolism elucidated in the last ten years, in particular aspects not generally covered in biochemistry texts, e.

The Oxidation of Sulfur-Containing Amino Acids by L-Amino Acid Oxidases
1982L-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 ...
