On the basis of three kinds of indices of physicochemical properties of twenty amino acids, a novel 3D graphical representation of protein sequences is presented. Then, the improved cumulative distance of the 3D graphical representations is defined in order to compare the proteins for...

Based on three physicochemical properties of amino acid side chains, we proposed a novel unique 3D graphical representation of protein sequences. Then, we constructed two vectors of three components as mathematical objects to characterize protein sequences numerically. The...

Based on a five-letter model of the 20 amino acids, we propose a new 3-D graphical representation of protein sequence. Then we derive from the graphical representation, numerical indices called 3-D coupling numbers, to characterize protein sequences. The examination of the...

Graphical representation of DNA sequences provides a simple and intuitive way of analyzing and sorting various gene sequences. It is attractive to researchers to propose much more appropriate methods. In this study, a new graphical representation is presented. The method adopts the CMI coding to...
