The oxidation of peptidyl-L-methionine to peptidyl-L-methionine sulfone. The oxidation of the terminal amino-methylene groups of peptidyl-L-lysine or peptidyl-5-hydroxy-L-lysine to aldehyde groups to form allysine or hydroxyallysine residues, respectively; these are intermediates in the formation of covalent cross-links between adjacent polypeptide chains in proteins such as collagens. The oxidation of allysine to 2-aminoadipic acid. The oxidation of peptidyl-cysteine to peptidyl-L-cysteine sulfinic acid or peptidyl-L-cysteine sulfenic acid. The modification of a protein amino acid by oxidation. The posttranslational oxidation of peptidyl-tryptophan to form tryptophan-6,7-dione, otherwise known as tryptophyl quinone, which is further modified by cross-linking to either tryptophan or cysteine. The modification of a lipoprotein by oxidation of one or more amino acids in the protein. The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications). Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification). The covalent alteration of one or more amino acids occurring in a protein after the protein has been completely translated and released from the ribosome.
