Fig 7. MS/MS spectrum of a 4+ charged cross-link at m/z 428.986, identified in photo-cross-linking experiments with the PPAR β/δ variant F180Bpa.

Fig 7

The cross-link was unambiguously identified between Bpa-180 and Ile-379, based on the y2 ion at m/z 288.205, the y3 ion at m/z 469.780, and the b8 ion at m/z 704.366.
