Abstract

The paper obtains fuzzy representation of amino acids using corresponding fuzzy representation of DNA sequences, the latter being represented on I12 (unit hypercube of dimension 12). A protein sequence is represented by a 240×20 matrix. Of the 240 elements of each row representing an amino acid, only 12 components have non-zero fuzzy values, others have zero values only. On the represented matrix, consisting of 20 rows of amino acids separately, attempt is made to find similarities of the amino acids on the basis of the lengths of 240 component vectors of each of them. This leads to six groups of amino acids, which are different from one another, but each such group has its components similar to each other. Using separate symbols for each such group, a protein sequence is finally represented in the form of six different symbols. This may help in the numerical representation of protein sequences.
