a

See Fig. 1 and Eq.1 as well as the relevant text for the definitions of the subsets listed in this table.

b

See Eqs.2–3 for the definition about the number of virtual proteins, and its relation with the number of different proteins.

c

Of the 7,766 different proteins, 6,687 belong to one subcellular location, 1,029 to two locations, 48 to three locations, and 2 to four locations. See Online Supporting Information S1 for the protein sequences.
