title: Amino acid composition and protein dimension.
abstract: There is indirect evidence that the amino acid composition of proteins depends on their dimension. The amino acid composition of a nonredundant set of about 550,000 proteins was determined and it was observed that, in the range of 50-200 residues, the percentage of occurrence of most of the residue types significantly depends on protein dimension. This result should prove useful in analyzing protein sequences and genomics.
