Table 1 E1 phosphate sites identified by MS analysis and site characteristics. Phospho-amino acid positions identified in this study are shown in the left column, followed by the sequence of the surrounding amino acids. The phosphorylated position is highlighted in bold type. The NetPhos2.0 and NetPhosK scores for each phospho-amino acid is shown. 1.0 is the maximum score, and 0.5 is the default threshold for likely phosphorylation. The kinases predicted by the NetPhosK algorithm are shown. Where there is no NetPhosK score, that position was not predicted and the kinases were identified by manual analysis and comparison to published consensus sequences [44]. *, phosphate sites identified by MS and not previously known; **, phosphate sites identified by MS, confirming previously known sites.
