Proteins are made up of long chains of amino acids, and most proteins have one or more of the sulfur-containing amino acid methionine. Oxidation of the sulfur atom in methionine is an important ...

In normal cells, oxidation of methionine to a methionine sulfoxide is reversed by an enzyme that removes the oxygen atom — that is, reduces it.

Chemists have reported a new method for separation of methionine sulfoxide diastereomers that opens up new opportunities for studying their roles in biological processes.

Oxidation of the sulfur atom in methionine is an important biomolecular reaction that can have a wide range of biological consequences depending on the context and the protein involved. Chemists ...

All the latest science news on amino acid methionine from Phys.org. Find the latest news, advancements, and breakthroughs.

That enzyme, methionine sulfoxide reductase A (MSRA), turns out to be suppressed in pancreatic cancer cells, which allows oxidation to trigger tetramer formation and boost respiration of cancer ...

The protein, named methionine sulfoxide reductase A (MSRA), caught the attention of Dr. Chio and her colleagues due to its unusually low levels of expression in metastatic pancreatic cancer cells.
