Tryptophan tryptophylquinone (TTQ)^[1] is an enzyme cofactor, generated by posttranslational modification of amino acids within the protein. Methylamine dehydrogenase (MADH), an amine dehydrogenase, that requires TTQ for its catalytic function.^[2] It is found in the bacteria Paracoccus denitrificans.
