From: Circles within circles: crosstalk between protein Ser/Thr/Tyr-phosphorylation and Met oxidation
The percentage of Ser/Thr/Tyr sites (individually from left to right in each group) including a Met residue within ± 6 window in different taxa. On average, phosphorylated sites contain less Met compared to all Ser/Thr/Tyr sites in proteomes. In eukaryotes, Tyr sites contain proportionally more Met compared to Ser and Thr sites. The large deviation from the otherwise 'normal' pattern seen with bacteria and archaea is likely due to the small number of phosphorylated sites.
