Amino acid sequence, quantitative value of human transthyretin (TTR) peptides and schema of folding TTR based on previously reported data [7]. A. Transthyretin (TTR) consists of 127 amino acids. In a previous report using the cryo-EM [7], peptides aa 11–123 were detected (solid underlined) and 35–57 were not (dotted underlined). Two peptides, aa 22–34 (black and bold) and aa 36–48 (red and bold), which were detected using absolute quantification by LC–MS in our previous study [2] are enclosed in the boxes. B. We used two specimens from each patient: cardiac tissue (n = 9) and another organ (n = 7); however, two ATTR cases were excluded because the amount of deposition in organs other than the heart was too small (cases 15, 16). The bar graph shows the average of three measurements. In our quantification study, two tryptic peptides; aa 22–34 and aa 36–48 of TTR were successfully. Both fragments were detected in 47 of 48 samples, with an average aa 36–48/aa 22–34 ratio of 10.26% (2.45%–26.67%).The original data can be found in “Supporting information (S3 Table)” in reference [2]. C. This early fibril state consists of full-length TTR and contains the low amyloidogenic segment at aa 36–56 (including red part). Quantitative values of aa 36–48 indicated mature ATTR amyloid fibrils are 9 times more present than the early fibril state
