Development of web-based interface for visualization of protein-ligand interaction sites and their conservation

Proteins are fundamental building blocks of all living organisms. They perform their function by binding to other molecules. This thesis deals with interactions between proteins and small molecules (so called ligands) because most of the currently used drugs are small molecules. While there are several tools that can predict these interactions, they are almost none for their visualization. Thus, we built a new visualization website by combining several protein visualizers toge- ther. Since evolutionary homology correlates with binding sites, our web interface also displays homology for comparison. We developed several ways how to calcu- late homology, and used it to improve detection of protein-ligand binding sites in our experiments. Here we present PrankWeb, a modern web application for structure and sequence visualization of a protein and its protein-ligand binding sites as well as evolutionary homology. We hope that it will provide a quick and convenient way for scientists to analyze proteins.
