Purified proteins were subjected to SDS-PAGE, and the sliced gel pieces were processed for in-gel digestion and peptide elution (for data in parentheses), or the proteins were digested and eluted directly from protein-bound beads. The eluted peptides were injected for LC-MS analysis. The MS/MS data was searched with GPM X!Tandem software against the UniProt Arabidopsis database with P = 0.01.
