Dock Ten Million Molecules with Gigadock Warp and Analysis with Freeform Consensus

In this tutorial ten million molecules will be selected at random from the Enamine Diverse database and docked to the heat shock protein 90 (HSP90) target using the Gigadock Warp floe. The Freeform delta G values for the top docked molecules will be calculated with the FreeForm Pose floe and a consensus hit list of the best docked scores and Freeform delta G values will be generated with the Pareto Frontier Consensus.

Running all the Floes in this tutorial will cost approximately $50 in Orion compute charges; the cost will vary somewhat depending on current Amazon Web Services (AWS) pricing.

This tutorial uses the following Floes:

Create a Tutorial Project and Working Directory

Note

If you have already created a Tutorial project while doing another tutorial you can re-use the existing one and skip this step.

  1. Log into Orion

  2. Click the Home button at the top of the left menubar.

  3. Click on the ‘Create New Project’ button and in the pop up dialog enter Tutorial for the name of the project and click ‘Save’.

Prepare Design Unit / Receptor

Note

If you have prepared this design until for another tutorial you can skip this step and re-used the design unit from the first tutorial.

This tutorial will use the HSP90 crystal structure 1uyg from the Protein Data Bank. To import this structure into Orion and prepare it for docking locate the floe Classic Spruce - Prep from PDB Codes Floe in the ‘Floes’ page as follows

  1. Click on the ‘Floes’ button in the left menu bar

  2. Click on the ‘Floes’ tab

  3. Set the ‘Browse Workfloes’ drop down menu to ‘Show all packages’

  4. Select ‘All’ under Browse Workfloes

  5. In the search bar enter Spruce

A list of three spruce Floes will now be visible to the right. Click on the Classic Spruce - Prep from PDB Codes and a Job Form will pop up. Specify the following parameter settings in the Job Form.

  • Job Properties

    • Output Path : Tutorials/My Data/Input Data

      You will need to create the Input Data subfolder unless you have already created it in another tutorial (this can be done within the selection menu).

  • Promoted Parameters

    • Outputs

      • Dataset : hsp90_design_unit

    • PDB Codes(s) to Download : 1uyg

Click the ‘Start Job’ button to launch the Floe. Wait for the Floe status to be complete before moving on to the next step in the tutorial (this may take ~10min). The cost will be less than $1.

View Prepared Design Unit / Receptor

Once the Classic Spruce - Prep from PDB Codes job finishes make the resulting dataset active as follows:

  1. Go to the Project Data page by clicking on the blue ‘Data’ button on the left menubar.

  2. Select ‘My Data’ under ‘Project Data’ from the list of options to the left of the page.

  3. Select the folder ‘Input Data’ in the main view

  4. In the ‘Show’ menu in the top center of the screen check ‘Datasets’ if it is not already checked.

  5. Check to make sure you have no datasets set as active by clicking on ‘Active Datasets’ in the top right of the window. If you do click ‘Clear All’ to clear them.

  6. Make the hsp90_design_unit active by clicking on the circle with the plus symbol in the Active column next to the hsp90_design_unit name.

Now switch to the 3D Viewer by clicking on the 3D button in the left menu bar. Only the crystallographic ligand from the pdb structure will initially be visible. Do the following to make the receptor information in the design unit visible in the 3D view.

  1. In the ‘All Data’ window expand the tree under ‘1UGY(A) > PU(A-1224)’ by clicking on the chevron immediately to the right of the name.

  2. Expand the tree under ‘1UGY(A) > PU(A-1224)’ by clicking on the chevron immediately to the right of the name. Note: the ‘1UGY(A) > PU(A-1224)’ name appears twice, once by default and once again after completing step 1.

  3. Expanded tree under ‘Receptor’ by clicking on the chevron immediately to the right.

  4. Click the check button to the left of “Receptor Outer Contour” to make the contour visible in the 3D window.

The protein structure, crystallographic ligand and a blue contour are now visible. The blue contour (generally referred to in OpenEye documentation as ‘The Outer Contour’) encloses the region of space that all docked molecule heavy atoms will fit within.
