![]() ![]() This exercise is supposed to quantify this. This is a form of cross-validation of methods since one could expect that the group that samples the poses also performs better scoring. The scorers are then supposed to re-rank the poses. Scorers: The community contributes sets of poses (unranked) for each target.This tests the automated capacity to model protein-protein models. Servers: Participants are given the unbound structures or sequences of one or both interacting partners that are supposed to be submitted to an automatic server which needs to return the results (ideally) within 24 hours.This tests the current ad hoc capacity to model protein-protein complexes. Predictors are then supposed to submit a ranked list of modeled complexes which can be achieved by any docking/prediction tools and some human intervention. Predictors: Participants are given the unbound structures or sequences of one or both interacting partners.The latest round of the experiment is particularly interesting as it challenged the participants with affinity prediction which is going one step beyond modeling protein-protein complexes.įor those that are not very familiar with CAPRI, one can participate in any of the following roles: It covers the results of the participation of the pyDock group in CAPRI. The docking calculation can be started using the default parameters moreover, it is also possible to manually set docking parameters for more advanced users.įinally, 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.We have discussed a paper highlighting the latest progress in the field of protein-protein docking. 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 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. Besides single ligands, multiple ligands in sdf files can also be uploaded so that to enable high throughput docking of ligand libraries. The ligands can be directly downloaded from PubChem database, uploaded or drawn in. More accurate protein partial charge calculation using quantum chemical methods. 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 (Small molecules present in the pdb files can be added to the ligand folder. DOCK IT SOLVES PROTEIN WINDOWSFeaturesĭocking Server windows are organized into three modules following the basic steps of docking calculations DOCK IT SOLVES PROTEIN SOFTWAREThus, 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. accurate ligand geometry optimization, energy minimization, charge calculation, docking calculation and protein-ligand complex representation. 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.ĭockingServer integrates a number of computational chemistry software specifically aimed at correctly calculating parameters needed at different steps of the docking procedure, i.e. DOCK IT SOLVES PROTEIN FULLWhile 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. DockingServer offers a web-based, easy to use interface that handles all aspects of molecular docking from ligand and protein set-up. ![]()
