I have recieved several replies on the PROTEINS board concerning
the tools out there for predicting surface residues. I have presented
here the relevant references and suggestions.:-)
My thanks to all those who replied and made this information available.

Synthetic Peptides Inc. (c/o Dept. of Biochemistry, Univ. of Alberta, Edmonton,
Canada T6G 2H7) sells a PC program called SurfacePlot that predicts surface
residues. It is intended to identify stretches of sequence that could be useful
as synthetic antigens.

George Rose has published a number of papers on
predicting the location of turns in the peptide chain using (I recall
distantly and perhaps incorrectly) local minima in a smoothed
hydrophobicity term. See Nature 384:654-7 (1983) and Adv. Protein Chem
37:1-109 (1985) for more details. This is not precisely the
question you asked but is related because the turns are usually
on the surface.

perhaps PROFILEGRAPH will do what you need. It runs on a PC under MSDOS and
plots various amino acid parameters over one or more given sequences. Several
meaures of surface probability are included into the program. It will not
give clear statements like: "Pos.121 through 140 are on surface" but draws
only probability curves that should be used together with the original paper
given by the authors of the parameter table. (Refs. cited in program
The program is quite voluminous, but does a lot of other things too.
Is is available from netserv at embl-heidelberg.de by sending a mail with
an empty subject line which has in the mail-body the line:
I hope you can use the program,

I noticed your posting on bionet.molbio.proteins (or whatever) requesting
a program for prediction of surface residues. It turns out that my advisor
wrote a program to predict 'flexible' residues of proteins, which turns out
to be essentially identical to predicting surface residues. The listing of
this fairly short FORTRAN program appears in:
