Introduction

  • NOTE: these tutorials did not get finished before the paper appeared in J Med Chem. Please manage as best you can until we write them properly*

We have tried to identify projects that are *representative* of common projects, *illustrative* of the features and weaknesses of DOCK Blaster as it currently stands, and *didactic*, in as much as they illustrate how we imagine this service should be used.

You do not need to run a tutorial before you use DOCK Blaster, but we recommend it and it will not take long. Scan the list and try to pick an example that resembles your current project, in terms of available information and perhaps target class, ligand chemistry, or binding site situation. Please see also the preliminary considerations article for the "big picture". The categories of targets we will consider are: nuclear receptor, enzyme, metallo-enzyme, kinase, GPCR. The types of problems we consider are : good information, minimal information, insufficient information, and excessive information. The level of effort for the tutorial is either easy, moderate, or hard.

Dock to human thyroid hormone beta-1

  • Target category: Nuclear receptor
  • Effort: Easy
  • Problem type: Minimal information
  • PDB code: 1N46

Dock to minearalocorticoid receptor (MR)

  • Target category: Nuclear receptor
  • Effort: Medium
  • Problem type: Minimal information
  • PDB code: XXXX

A nuclear hormone receptor, drawn from DUD, that illustrates the use of DOCK Blaster when both actives and inactive controls are available.

Dock methotrexate (MTX) to dihydrofolate reductase (DHFR)

  • Target category: Nuclear receptor
  • Effort: Medium
  • Problem type: Minimal information
  • PDB code: XXXX

This is a classic case from the history of molecular docking, also from DUD with an extensive literature. It serves to illustrate the use of a co-factor bound to the target.


Dock to angiotensin II converting enzyme (ACE)

  • Target category: Nuclear receptor
  • Effort: Medium
  • Problem type: Minimal information
  • PDB code: XXXX

This case, also from DUD, illustrates the use of DOCK Blaster on zinc metalloenzymes.

Only apo structure available

  • Target category: Nuclear receptor
  • Effort: Medium
  • Problem type: Minimal information
  • PDB code: XXXX

DOCK to cruzain, a cystein protease target for Chagas' Disease, for which only an apo structure is available. Describes both modeling a ligand in, and using protein residues in the binding site to indicate the binding site. Lack of diagnostics because of no available ligand.

No crystal structure available

  • Target category: Nuclear receptor
  • Effort: Medium
  • Problem type: Minimal information
  • PDB code: XXXX


DOCK to a target for which no crystal structure is available. Describes the use of Blast/Modbase to obtain and evaluate a structure. Describes checking the model of the target for suitability for docking.

Multiple crystal structures available

  • Target category: Nuclear receptor
  • Effort: Medium
  • Problem type: Minimal information
  • PDB code: XXXX


Multiple crystal structures available. Multiple actives and inactives available. How to optimise the use of DOCK Blaster for this case.
