I wonder if there is any already available programs that can
look through all the protein sequences in the protein database
(e.g. PIR/NBRF, or SWISSPROT) and calculate (say) % Cys and then
output a frequency table e.g.
No of proteins with between 0.0% and 0.1% Cys
No of proteins with between 0.1% and 0.2% Cys
etc
etc
No of proteins with between 99.9% and 100.0% Cys
I'm interested in biased amino acid composition.
