What is Z dock?

The ZDOCK Server allows users to generate sets of predictions in PDB format from job output files with a Java program. The ZDOCK and M-ZDOCK executables and code were not modified for the server from the downloadable and published algorithms; default sampling levels are used for all jobs.

What is shape complementarity?

The shape complementarity is a geometric descriptor, stemming from the practical observation that protein surfaces are complementary to each other at the binding interface. Generally speaking, the shape complementarity can be defined as the match of the convex surface and concave surface of the proteins.

What is PatchDock server?

PatchDock is an algorithm for molecular docking. The input is two molecules of any type: proteins, DNA, peptides, drugs. The output is a list of potential complexes sorted by shape complementarity criteria. Short Overview: Once the patches are identified, they can be superimposed using shape matching algorithms.

Which tool is used for molecular docking?

Over the last two decades, more than 60 different docking tools and programs have been developed for both academic and commercial, use such as DOCK (Venkatachalam et al. 2003) AutoDock (Österberg et al. 2002), FlexX (Rarey et al. 1996), Surflex (Jain 2003), GOLD (Jones et al.

Which protein is called docking?

Docking proteins associated with activated RTKs include FGF receptor substrate 2 (FRS2α), insulin receptor substrate 1 (IRS1), and the Grb2 (Growth factor receptor bound protein 2)-associated binder (Gab1).

How do you dock two proteins?

break the molecule to be docked into several pieces, and dock each one separately. Then, look for docked conformations that would be consistent with the entire molecule. This method was used many years ago to dock two proteins using AutoDock. dock a small portion from one end of the molecule.

What is shape complementarity in docking?

Shape complementarity is the most basic component of a scoring function and plays an important role in protein-protein docking. Despite significant progresses, shape representation remains an open question in the development of protein-protein docking algorithms, especially for grid-based docking approaches.

How do you read PatchDock results?

The higher the value, the smaller the number of the results you get. The recommended values are 4A for protein-protein docking and 1.5A for protein-small molecule docking. Complex Type: PatchDock has different sets of paramerters, optimized for different types of complexes.

Why is PatchDock used?

PatchDock (20) is a geometry-based molecular docking algorithm. It is aimed at finding docking transformations that yield good molecular shape complementarity. Such transformations, when applied, induce both wide interface areas and small amounts of steric clashes.

Which software is used for docking?

What are the steps in docking?

Following, we will describe the four-step procedure adopted in this study to perform the molecular docking.

  1. 3.1. Target selection.

  5. 3.5. Docking software description.

How is shape complementarity used in protein docking?

Shape complementarity is the most basic ingredient of all scoring functions for docking. As the name implies, it is a geometric descriptor, stemming from the practical obser-vation that protein surfaces are complementary to each other at the binding interface. However, the exact formula for shape complementarity differs among docking algo-

How to see the docking predictions in ZDOCK?

Visualization: A JMol-enabled visualization window shows the top 5 docking predictions, and for ZDOCK output, the ligand center-of-mass of the the top 500 can also be viewed. For ZDOCK, the first PDB file specified by the user on the submission page is treated as “receptor” and is fixed in output visualization.

What is the atom type of ZDOCK server?

More Details: The ZDOCK server gives an atom type of 19 to all atoms in residues selected for blocking, which is a dummy atom type with strongly unfavorable ACE or IFACE contact energy. This significantly lowers the chance of that residue being in the predicted binding site.
