A yeast with unusual sulphur amino acid metabolism.

Sulphur Metabolism of Yeast.

Two general conclusions are warranted as to the sulphur metabolism and nutrition in animals. The first is that although most of the sulphur taken into the system is in the reduced form, that is, mainly as cystine or possibly also as cysteine, nevertheless the main end product of normal sulphur metabolism is the completely oxidized sulphate form. This is well established by numerous investigatio...

Reesponse of laying hens fed on different dietary sulphur amino acid supplemented with maize oil

Stimulatory effect of sulphide on thiotaurine synthesis in three hydrothermal-vent species from the East Pacific Rise.

Symbiotic associations between marine invertebrates and sulphur-oxidising bacteria are a common feature in communities from sulphide-rich environments, such as those flourishing in the vicinity of hydrothermal vents. While the bacterial endosymbionts provide the host with an undoubted nutritional advantage, their presence also requires specific adaptations for the transport and storage of sulph...

The Amino Acids of Alfalfa as Revealed by Paper Chromatography with Special Reference to Compounds Labelled with S.

This investigation is essentially a collaboration between two laboratories bringing together problems in which each is interested. The Department of Agricultural Research of the American Smelting and Refining Company has long been interested in the problems of sulphur toxicity and sulphur metabolism in plants which are economically important. In the course of this work investigations have been ...

The amino acid sequence of protein SCMK-B2C from the high-sulphur fraction of wool keratin.

1. The amino acid sequence of a protein from the reduced and carboxymethylated high-sulphur fraction of wool has been determined. 2. The sequence of this S-carboxymethylkerateine (SCMK-B2C) of 151 amino acid residues displays much internal homology and an unusual residue distribution. Thus a ten-residue sequence occurs four times near the N-terminus and five times near the C-terminus with few c...
