FIGURE 3.

Product ion (tandem MS/MS) spectra of peptides that were predicted to be cross-linked between RDGVDSSGRKPTGKGVY37 from PsbR and KL28 from PsbP (A) and ESSTPVVDGKQYY127 and FKGAKKF175 from PsbP and GANCGPEAVW99 from CP26 (B). Prime and asterisk show unhydrated and deammoniated product ions, respectively. Note that for clarity not all product ions assigned by Mass Matrix are labeled. Complete sets of the assigned product ions are listed in supplemental Tables S7 and S8. Insets are the respective precursor ion spectra. a.u., arbitrary units.
