When conservation of N- acetylated CysLys pairs relative to non-acetylated CysLys pairs was plotted against the maximum lifespan of 52 mammal and bird species, there was a highly significant negative correlation (p < 0.0001) and no significant correlation for N- acetylated cytosolic SerLys pairs (p = 0.32; Figure S3 A).
