About DockingServer
DockingServer offers a web-based, easy to use interface that handles all aspects of molecular docking from ligand and protein set-up.
While its user friendly interface enables docking calculation and results evaluation carried out by researchers coming from all fields of biochemistry, DockingServer also provides full control on the setting of specific parameters of ligand and protein set up and docking calculations for more advanced users.
The application can be used for docking and analysis of single ligands as well as for high throughput docking of ligand libraries to target proteins.
DockingServer integrates a number of computational chemistry software specifically aimed at correctly calculating parameters needed at different steps of the docking procedure, i.e. accurate ligand geometry optimization, energy minimization, charge calculation, docking calculation and protein-ligand complex representation. Thus, the use of DockingServer allows the user to carry out highly efficient and robust docking calculations by integrating a number of popular software used in in silico chemistry into one comprehensive web service.
Features
The proteins can be uploaded as a pdb file, or can directly be downloaded (after keyword search in the database if needed) from Protein Data Bank (www.rcsb.org). Small molecules present in the pdb files can be added to the ligand folder. More accurate protein partial charge calculation using quantum chemical methods.
The ligands can be directly downloaded from PubChem database, uploaded or drawn in. Besides single ligands, multiple ligands in sdf files can also be uploaded so that to enable high throughput docking of ligand libraries.
The user can chose the desired pH affecting the protonation state of the ligand and whether semiempirical charges and optimization should be carried out during the process of ligand preparation.
In the docking window multiple ligands and/or dockings so that invidiual docking calculation as well as virtual high throughput screening can be carried out. The docking calculation can be started using the default parameters; moreover, it is also possible to manually set docking parameters for more advanced users.
Finally, docking results are automatically processed in different ways to offer better understanding of the results: 1, resulting docking energies, frequencies and downloadable pdb coordinates are summarized in a table; 2, figures of the calculated ligand-protein complexes are automatically generated by VMD or can be manually rendered using the Jmol applet; 3, ligand-protein interaction tables are automatically generated that helps identify the driving forces of the complexation; 4, The applied methods and the according references are summarized.
Pricing and Availability
Registration is required for a private workspace. Quantum chemical treatment of the input files, data storage of the input and output files, e-mail and forum support are available upon subscription (see pricing). Free limited access is provided without registration using a common workspace. Sales issues please e-mail our sales team or contact our head office.
