Mass spectra of <i>Pf</i>CCT MΔK^WT and <i>Pf</i>CCT MΔK^R681H proteins under native electrospray conditions.

<p>M and D indicate signals contributing monomers and dimers, respectively, while numbers denote the charge states. A) Mass spectrum of <i>Pf</i>CCT MΔK^WT measured in the present study for direct comparison (cf. also [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129632#pone.0129632.ref010" target="_blank">10</a>]). B) Mass spectrum of <i>Pf</i>CCT MΔK^R681H. In the inset the 10-times enlarged graph of dimer regions (3150–4000 m/z) is shown.
