The chemical reactions and pathways resulting in the breakdown of compounds that contain sulfur, such as the amino acids methionine and cysteine or the tripeptide glutathione. The chemical reactions and pathways involving the catabolism of branched chain amino acids to produce branched chain alcohols with one carbon less than the starting amino acid. In S. cerevisiae, this is known to occur for leucine, isoleucine, valine, methionine, phenylalanine, tyrosine, or tryptophan. When methionine is used as the substrate, 3-methylthiopropanol is produced. Often referred to as the Ehrlich pathway, these reactions generally occur during fermentation to produce a variety of alcohols, often collectively referred to as fusel alcohols. Depending on the redox state of the cells, carboxylic acid derivatives may be produced instead of alcohols. The chemical reactions and pathways involving amino acids containing sulfur, comprising cysteine, homocysteine, methionine and selenocysteine. The chemical reactions and pathways resulting in the breakdown of amino acids containing sulfur, comprising cysteine, methionine and selenocysteine. The chemical reactions and pathways involving the catabolism of amino acids to produce carboxylic acids with one carbon less than the starting amino acid. In S. cerevisiae, this is known to occur for leucine, isoleucine, valine, methionine, phenylalanine, tyrosine, or tryptophan. When methionine is used as the substrate, 3-methylthiopropanoate is produced. Often referred to as the Ehrlich pathway, these reactions generally occur during fermentation to produce a variety of carboxylic acids, sometimes collectively referred to as fusel acids. Depending on the redox state of the cells, alcohol derivatives may be produced instead of carboxylic acids. The chemical reactions and pathways resulting in the breakdown of amino acids of the aspartate family, comprising asparagine, aspartate, lysine, methionine and threonine. The chemical reactions and pathways involving methionine (2-amino-4-(methylthio)butanoic acid), a sulfur-containing, essential amino acid found in peptide linkage in proteins. The chemical reactions and pathways involving amino acids of the aspartate family, comprising asparagine, aspartate, lysine, methionine and threonine. The chemical reactions and pathways resulting in the breakdown of amino acids, organic acids containing one or more amino substituents. The chemical reactions and pathways resulting in the breakdown of methionine into other compounds, including succinyl-CoA. The chemical reactions and pathways resulting in the breakdown of methionine (2-amino-4-(methylthio)butanoic acid), a sulfur-containing, essential amino acid found in peptide linkage in proteins. The chemical reactions and pathways resulting in the breakdown of methionine, via the intermediate 2-oxobutanoate.
