Fig. 10.

Relative spectral counts and subplastidial localization for selected functional classes. The size of the spots is proportional to the number of proteins having the same relative spectral count distribution between envelope, stroma, and thylakoids fractions. A, how to read the diagrams. x axis, percentage of spectral count corresponding to envelope fractions; y axis, percentage of spectral count corresponding to stroma fractions; yellow box (ENV), proteins that are mainly localized in the envelope; orange box (STR), proteins that are mainly localized in the stroma; green box (THY), proteins that are mainly localized in the thylakoids. B–H, diagrams showing the subplastidial localization, based on spectral count, for some functional classes as defined by MapManBin (42) (see supplemental Data 9, column “MapManBin”). The functional classes considered are transport (B), amino acid metabolism (C), photosystems (D), not assigned (E), protein degradation (F), protein synthesis (G), and Calvin cycle (H).
