TTR uses FAD as cofactor. Relevance TTR is found only in parasitic protozoa, hence its inhibitors are used as effective drugs against diseases like Chagas Disease caused by the parasites Trypanosoma and Leishmania[1]. Structural highlights The contains residues which are part of the electron transfer function of the enzyme and the bound TPT substrate[2].
