Abstract

Antibodies play a significant role in the immunotherapy, basic research and the pharmaceutical industry. Nowadays, both DNA recombinant technology and antibody engineering technology are widely used in many fields such as diagnostics, therapeutics, drug targeted delivery, and research reagents. Computational docking of antigen-antibody complexes and analysis of atomic interactions are important to find effective B-cell epitopes and new antibodies with appropriate properties. In the present study, by using ClusPro 2.0 webserver, docking the antigen (factor H binding protein (fHbp)) to the novel-selected scFv antibody was performed. By analyzing the fHbp-scFv complexes, important amino acids were identified. After docking, peptides Ala192-His198, Asp 211-216, and Gly229-Ser228 of the fHbp antigen were recognized as essential interactive regions to the scFv antibody. Results obtained from our bioinformatics study are important and give us the basis for the favored designs of new molecules such as effective B-cell epitopes targeted by neutralizing antibodies for vaccine design. © 2017 World Scientific Publishing Company.
