Figure 2.

Overlay of apo and ligand-bound protein complex mass spectra for (A) CRP and (B) CTB. Highest intensity apo and ligand-bound species (charge state 18+ for CRP and 11+ for CTB) are highlighted as inset. Ligand-bound pentamers selected for CID and SID are emphasized by light blue. Apo and ligand-bound protein complex mass spectra are colored red and black, respectively. Deconvoluted spectra can be found in the Supporting Information along with detailed labeling of all observed species (Figure S3).
