pI and Cys content of the expanded curated lumenal, thylakoid membrane and inner envelope membrane proteome. A, Frequency distribution of the pI for the full-length and processed curated proteomes (full-length, white squares, cTP removed, black squares, and cTP and lTP removed, black triangles). B, Frequency distribution of proteins in the three curated proteomes based on the number of Cys residues. Membrane sets are the same as used in Figures 1 and 2, and the lumenal set contained 51 proteins (see Supplemental Table I).
