Extended Data Fig. 4. Protein deamidation for all hominin specimens in Ranis.

Extended Data Fig. 4

a) Deamidation rate of COL1A1 508–519 for hominin specimens in the 2016–2022 and 1932–1938 excavations with ZooMS (layer X, n = 4 NISP; layer 8, n = 3; layer 9, n = 1), b) Glutamine (Q) deamidation plot for hominin specimens in the 2016–2022 and 1932–1938 excavations analysed with directDIA SPIN (layer X, n = 4; layer 8, n = 3), and c) Asparagine (N) deamidation plot for hominin specimens in the 2016–2022 and 1932–1938 excavations analysed with directDIA SPIN (layer X, n = 4; layer 8, n = 3). The hominin specimen recovered from layer 9 was not included in the SPIN analysis (plots b and c). For panel a, 1 indicates no deamidation of N or Q, while 0 indicates complete deamidation of N or Q. For panels b and c, 0 indicates no deamidation of N or Q, while 1 indicates complete deamidation of N or Q. The box plots within the violin plots define the range of the data (whiskers extend to 1.5× the interquartile range), outliers (black dots, beyond 1.5× the interquartile range), 25th and 75th percentiles (boxes), and medians (centre lines).
