(A) nanoESI-QTOF mass spectra of jrPPO1(Asp101 → Arg445). Inset(A): Peaks of charge state [33] to [38] magnified. (B) Zoomed section of charge state [36] and [37]. Masses of species C–D: C = 38,890 Da, D = 39,047 Da; Mass difference between species fit to distinct amino acid composition indicated in amino acid letter code. Inset(B): Highly zoomed figure of charge state [36] showing clearly shoulders corresponding to mass differences of 16 or 32 Da (oxidation).
