Proteins play an important role in cell functions. Protein structures are useful for determining its functions. Dihedral angle places an important role in determining the structure of proteins. The aim of encoding the angle of dihedral or torsion angle is done with respect to the plane of two angles. This paper explains encoding the dihedral angle of amino acids in a protein by applying the mathematical representation of determining dihedral or torsion angle with respect to the plane of two angles. By calculating the cross product and dot product of two vectors of amino acid the dihedral angle are determined. © TJPRC Pvt. Ltd.
