(a) Subcellular localization prediction using PSORTb: cytoplasmic (CYT), inner membrane (IM), extracellular (EXTRA), outer membrane (OM), and periplasmic (PERI). (b) Pie chart showing the distribution of predicted export signals among proteins identified by top-down MS. One predicted PERI protein with no detected export signal is designated as “Other.” (c) JCVI annotated functional categories of intact proteins identified using top-down analysis. (d) Pie chart representation of protein modifications observed by top-down MS.
