Passive residues are those that contribute for the interaction, but are deemed of less importance. Throughout the simulation, these active residues are restrained to be part of the interface, if possible, otherwise incurring in a scoring penalty. Generally, active residues are those of central importance for the interaction, such as residues whose knockouts abolish the interaction or those where the chemical shift perturbation is higher. AIRs are defined through a list of residues that fall under two categories: active and passive. These allow the translation of raw data such as NMR chemical shift perturbation or mutagenesis experiments into distance restraints that are incorporated in the energy function used in the calculations. Moreover, the intimate coupling with CNS endows HADDOCK with the ability to actually produce models of sufficient quality to be archived in the Protein Data Bank.ДЄ central aspect to HADDOCK is the definition of Ambiguous Interaction Restraints or AIRs.

What distinguishes HADDOCK from other docking software is its ability, inherited from CNS, to incorporate experimental data as restraints and use these to guide the docking process alongside traditional energetics and shape complementarity. HADDOCK (see ) is a collection of python scripts derived from ARIA ( ) that harness the power of CNS (Crystallography and NMR System вЂ“ ) for structure calculation of molecular complexes.

In order to run this tutorial you will need to have the following software installed: PyMOL.ДЄlso, if not provided with special workshop credentials to use the HADDOCK portal, make sure to register in order to be able to submit jobs. This is a question prompt: try answering it! This an instruction prompt: follow it! This is a PyMOL prompt: write this in the PyMOL command line prompt! Throughout the tutorial, coloured text will be used to refer to questions or instructions, and/or PyMOL commands. The HADDOCK web server for data-driven biomolecular docking. The HADDOCK2.2 webserver: User-friendly integrative modeling of biomolecular complexes. For this tutorial, we will only make use of inteface residues identified from NMR chemical shift perturbation data as described in Wang et al, EMBO J (2000).ДЇor this tutorial we will make use of the HADDOCK2.4 webserver.ДЄ description of the previous major version of our web server HADDOCK2.2 can be found in the following publications: These NMR experiments have also provided us with an array of data on the interaction itself (chemical shift perturbations, intermolecular NOEs, residual dipolar couplings, and simulated diffusion anisotropy data), which will be useful for the docking. The structure of the native complex has also been determined with NMR (PDB ID 1GGR).

It will take a few seconds to set the image, then click on вЂ SaveвЂ.

For a good resolution image, click on вЂ Ray (slow)вЂ and вЂ Draw (fast)вЂ for the average quality of the image.

It is up to you whether you want a transparent background or not.

You can set it to inches, the default units are in cm. If you want a good resolution image, then DPI at 300 from the dropdown.You will see a small dropdown showing width, height, units, etc.There you will see Reset, Zoom, Orient, etc. Set the display such as change the background color or protein color showing the best contrast so that the protein is clearly visible and set other things as per your requirements.Go to File -> Open -> Select an input PDB file. Open Pymol by typing Pymol in a terminal or by double-clicking the shortcut or by launching the Pymol app. In this article, we are going to save images in Pymol. We have provided several tutorials on Pymol. Pymol is a Python-based molecular viewer that is used for multiple purposes.
