On Uniform Representation of Proteins by Distance Matrix

We outline an approach that associates with each protein a 20×20 distance matrix, regardless of protein size. In this way, for the first time, all proteins are represented uniformly. The distance matrix is constructed from a lattice representation of proteins in which to each amino acid is assigned a pair of integer Cartesian coordinates by averaging the coordinates for all amino acids of the same kind. The new uniform representation of proteins is illustrated on ND6 proteins of chimpanzee. The possibility of using this novel distance matrix for a uniform nomenclature of proteins is also discussed.
