I have discovered a couple of independently published papers that
describe the amino acid composition of a protein that is of interest to
me. The approximate length of the protein is known in both cases and the
pI has been determined in one case. I'd like to identify the protein
from the composition data.
I'm aware of the AACompIdent program available at Expasy
(http://www.expasy.ch/tools/aacomp/), but I'm not convinced that it's
doing exactly what I want. As far as I can tell, AACompIdent does not
allow for the possibility that the protein whose composition you know
might be derived from a larger protein by post-translational cleavage.
What I'd like to do is a search similar to that carried out by
AACompIdent, but using a sliding window whose size is set by the user.
Any ideas?
Thanks.
