Protein structure comparison based on distances between secondary structure elements and backbone dihedral angles
Dobrinka Petrova · 2011
Protein secondary structure comparison combined with an alignment of backbone dihedral angles is proposed as an approach for protein structure similarity detection. The biological background of the method is presented. Rules for construction of the models of compared proteins are considered. A measure of dihedral angles distance is defined to service the angle comparison. A similarity measure, based on this definition, is suggested. Experiments are carried out to determine the influence of the backbone dihedral angles comparison on the final precision of similarity detection.
