Fragmentation of the +5 charge states of apo (868.0 m/z) and Zn1-HRGP330 (880.5 m/z) by CID and ETD/PTR. Fragmentation schemes are derived from analysis of spectra shown in Supplementary Figs S9–S11 and S13, using Biotools v3.2 and Sequence Editor v3.2, or manual peak assignments in the case of ETD/PTR for 880.5 m/z, where only weak fragment peaks were obtained. The boxes shaded in grey indicate areas where cleavage efficiency decreased dramatically upon zinc binding.
