Figure 5.
a) RPR and RPP21•RPP29 in 500 mM NH4OAc and 10 mM Mg(OAc)2. b) RPR and POP5•RPP30 in 500 mM NH4OAc and 6 mM Mg(OAc)2. In both a and b, the dominant peaks correspond to the RPR bound to one copy of the respective binary RPP complex. Collision-induced cleaning was used to partially remove non-specific adducts, providing better resolved peaks with optimal collision voltage at 110 V.
