a

The PSORT predictions for each site are given in a decimal form, 0 to 1.0, that is related to the strength of the prediction but is not an actual probability; for a given protein, they never add up to 1 for the sum of the different sites. All of these proteins show a “0” prediction for the cytoplasm.

b

Amino acids in the predicted membrane domain of each protein are listed.

c

Cut site refers to the position(s) at which the predicted leader peptide would be cleaved.

d

not M, P, S: not predicted by MaxH, PSORT or SOSUI, respectively. M, SOSUI, inner membrane location predicted by these programs. lpp, lipoprotein. See the text for the URL and description of the output for each program.
