a) C = cytoplasmic, CM = cytoplasmic membrane, P = periplasmic, OM = outer membrane, EC = extracellular, and UN = unknown.

b) Percentage of agreement is defined by graphic file with name 1471-2164-6-162-i1.gif, where: A represents the number of proteins of the fraction X predicted by PSORTb to be resident at X and X/Y localization sites.

B represents the total number of proteins of the fraction X predicted as not unknown by PSORTb.

c) Percentage of coverage is defined by graphic file with name 1471-2164-6-162-i2.gif, where: B represents the total number of proteins of the fraction X predicted as not unknown by PSORTb.

T represents the total number of proteins identified in the fraction X.
