Multiple inputs control sulfur-containing amino acid synthesis in Saccharomyces cerevisiae
In Saccharomyces cerevisiae, transcription of the MET regulon, which encodes the proteins involved in the synthesis of the sulfur-containing amino acids methionine and cysteine, is repressed by the presence of either methionine or cysteine in the environment. This repression is accomplished by ubiquitination of the transcription factor Met4, which is carried out by the SCF(Met30) E3 ubiquitin l...
متن کاملSulfur-containing amino acid requirement of rapidly growing steers.
Eight ruminally cannulated steers (294 kg, ADG = 1.3 kg/d) were used in a N retention study (8 x 8 latin-square design) to evaluate sulfur-containing (S) amino acid (AA) requirements for growth. Treatments were abomasal infusions of seven levels of L-methionine (0, 3, 6, 9, 12, 15 and 18 g/d) and one level of DL-methionine (6 g/d). All steers were fed a semipurified diet based on ammoniated cor...
متن کاملSulfur Metabolism and Sulfur-Containing Amino Acids: I- Molecular Effectors
The biology of the macro-element sulfur (S) is attracting an ever growing attention concerning cell physiology and human health. Sulfur metabolism works at the interplay between genetics and epigenetic as well as in the maintain of cell redox homeostasis. Indeed, unbalanced levels of S compounds in the body are actually under investigation as vulnerability factors and/or indicators of impaired ...
متن کاملAntioxidant effects of sulfur-containing amino acids.
Sulfur is an essential element for the entire biological kingdom because of its incorporation into amino acids, proteins and other biomolecules. Sulfur atoms are also important in the iron-containing flavoenzymes. Unlike humans, plants can use inorganic sulfur to synthesize sulfur-containing amino acids. Therefore, plants are an important source of sulfur for humans. Sulfur-containing compounds...
متن کاملLocalization and release of homocysteic acid, an excitatory sulfur-containing amino acid.
In addition to the excitatory role played by the amino acid transmitters glutamate and aspartate in the central nervous system, their sulfur-containing analogues homocysteic acid (HCA) and cysteine sulfinic acid (CSA) may also play a similar role. HCA is released and taken up by rat CNS tissue; it excites neurons predominantly via NMDA receptors whenever present, and is neurotoxic. The pattern ...
