Controlled Vocabulary

Allowed Value Details
ADP-ribose ADP-ribose protein modifications
Amino acid Canonical amino acid linked to a peptide residue
Biotin Biotin protein modifications
Carbohydrate Carbohydrate protein modifications
Chromophore/chromophore-like Chromophore or chromophore-like protein modifications
Covalent chemical modification A diverse range of chemical compounds that form covalent bonds with amino acids. Not covered by any of the other modification categories
Crosslinker Chemical modifications which covalently link two amino-acid residues. Excludes reaction intermediates and modifications covered by other modification categories
Flavin Flavin protein modifications
Heme/heme-like Heme or heme-like protein modifications
Lipid/lipid-like Lipid or lipid-like protein modifications
Named protein modification All protein modifications that are well defined into known types, have limited diversity, and are not explicitly covered by any other category. It includes PTMs, PCMs, rare amino acids and unnatural amino acids
Non-standard residue A diverse range of non-standard polypeptide residues that are not considered to be 'Named protein modifications'. These cannot be practically split into two CCDs, which describe the standard polypeptide residue and the modification group, and are not covered by any of the other modification categories
Nucleotide monophosphate Nucleotide monophosphate protein modifications
Terminal acetylation Terminal acetylation protein modification
Terminal amidation Terminal amidation protein modification
