Figure 3

Distribution of abundance of methylated proteins and half-life of lysine-methylated proteins, versus non-methylated proteins. a) The x-axis represents protein abundance, in copies per cell, as log base 10. The abundance of methylated proteins is represented with a solid line, while the abundance of non-methylated proteins is represented with a dotted line. b) The x-axis represents protein half-life, minutes, in log base 10. The half-life of lysine-methylated proteins is represented with a solid line, while the half-life of non-methylated proteins is represented with a dotted line. The arrow points to a group of proteins with very short half-life, seen only in 'other' proteins, which are likely to be unmethylated. Note that in both figures, 'other' proteins are those for which methylation was not found; this group may, however, contain some methylated proteins. Note also that abundance data and half-life data was not available for all yeast proteins in Belle et al. (2006) [53] and Ghaemmaghami et al. (2003) [50].
