Visualisation of tunnels in ChannelsDB using Mol*
Anotace
Tunely v proteínoch hrajú kľúčovú rolu v biologických systémoch, pretože umožňujú transport ligandov dovnútra a von z aktívnych miest enýmov a ovplyvňujú biochemické reakcie a terapeutické dôsledky. Databáza ChannelsDB, ktorá obsahuje metrické a fyzikálno-chemické vlastnosti biomolekulárnych kanálov a tunelov, poskytuje informácie o vlastnostiach ako dĺžka, polomer a ďalších rôznych charakteristikách …více
Abstract
Protein tunnels are crucial in biological systems, facilitating ligand transport to and from enzyme active sites and influencing biochemical reactions and therapeutic outcomes. ChannelsDB, a database cataloguing the metric and physicochemical properties of biomolecular channels and tunnels, offers insights into features such as length, radius, and other various properties important for biological function …více
Zadání práce
Proteins are the basic building blocks of living organisms. Proteins often react with other molecules (e.g. water, drugs), and this reaction takes place at the active sites of proteins. The active sites can be on the protein's surface or hidden inside. In the latter case, the molecules reach them through a tunnel that passes through the protein. Knowing the position and shape of the tunnel is thus essential for understanding the behaviour of proteins, for example, to determine whether a particular drug can pass through the tunnel and react with its active site.
In a collaboration between Masaryk University and Palacký University, the ChannelsDB database was developed. ChannelsDB contains tunnels computed for all known protein structures. The database allows the visualisation of tunnels inside proteins using the LiteMol software tool. However, this tool is now obsolete and no longer supported. Its modern alternative is Mol*, but it does not yet offer support for tunnel visualisation.
Thus, the thesis goals are the following:- Familiarise with ChannelsDB and its format for the representation of tunnels.
- Develop an extension to Mol* that would support the tunnel visualisation.
- Integrate the updated Mol* into the ChannelsDB.
