If such a residue does not belong in the interface there is no scoring penalty.
Passive residues are those that contribute for the interaction, but areĭeemed of less importance. Otherwise incurring in a scoring penalty. Throughout the simulation, these active residues are restrained to be part of the interface, if possible, Interaction, such as residues whose knockouts abolish the interaction or those where the chemical shift perturbation is Generally, active residues are those of central importance for the Under two categories: active and passive.
AIRs are defined through a list of residues that fall Incorporated in the energy function used in the calculations. Of raw data such as NMR chemical shift perturbation or mutagenesis experiments into distance restraints that are Moreover, the intimate coupling with CNS endows HADDOCK with theĪbility to actually produce models of sufficient quality to be archived in the Protein Data Bank.Ī central aspect to HADDOCK is the definition of Ambiguous Interaction Restraints or AIRs. Traditional energetics and shape complementarity.

What distinguishes HADDOCK from other docking software is its ability, inheritedįrom CNS, to incorporate experimental data as restraints and use these to guide the docking process alongside Power of CNS (Crystallography and NMR System – ) for structureĬalculation of molecular complexes. Is a collection of python scripts derived from ARIA ( ) that harness the Once downloaded, make sure to unpack the archive.

This an instruction prompt: follow it! This is a PyMOL prompt: write this in the PyMOL command line prompt! This is a Linux prompt: insert the commands in the terminal! Throughout the tutorial, colored text will be used to refer to questions or The HADDOCK web server for data-driven biomolecular docking. The HADDOCK2.2 webserver: User-friendly integrative modeling of biomolecular complexes. We will thus be making use of the results of the DisVis tutorial to setup variousĭocking runs using our HADDOCK2.2 webserver.Ī description of our web server can be found in the following publications: This is an additional information which might be useful to guide the docking. That it allows to identify the surface residues that are most often contacted in all possible models of the complex To evaluate the information content of MS cross-links and identify possible false positive. The tutorial builds on our DisVis tutorial (UniProtKB: O14250) and PUP2 (UniProtKB: Q9UT97).įor this complex seven experimentally determined cross-links (4 ADH & 3 ZL) are available The case we will be investigating is the interaction between two proteins of the 26S proteasome of S.
This tutorial will demonstrate the use of HADDOCK for predicting the structure of a protein-protein complex from MS cross-linking data.
