Figure 1

Native MS spectra of Pfu RPP21•RPP29 heterodimer (a) and (POP5•RPP30)2 heterotetramer (b) in 500 mM NH4OAc. In each spectrum, the dominant peaks and charge states are indicated. Asterisks indicate the 7+ and 8+ states of RPP29, a small amount likely generated from the binary complex during storage or analysis. See Table S-1 for predicted and observed masses.
