(left) Size exclusion chromatography of Ni-NTA purified complexes; peak A, tripartite and peak B, bipartite. For identification of proteins in peak A and B see Figure S7.
(middle, right) Deconvoluted native mass spectrometry (MS) spectra of the tripartite (middle) and bipartite (right) complexes- predicted molecular weights are indicated. For the original native MS spectra see FigureS7.
