Results from ProSMART can be visualised using either CCP4mg or PyMOL. ProSMART generates PDB files and PyMOL colour scripts that are used to display the results of a ProSMART comparative structural analysis. Various types of information are available for visualisation. Here, we will consider viewing substructure-based superpositions, colouring by local backbone conservation, and colouring by local side chain conformational dissimilarity. Loading Structures Into PyMOLР В РІР‚СњР В РІР‚РЋirst, load the PDB files output by ProSMART into PyMOL.

You should also know where the ProSMART results are located.Р В РІР‚СњР В РІР‚С›ssuming ProSMART has been executed using the ProSMART CCP4i GUI, follow these steps: ProSMART needs to have been executed before we can load the results into PyMOL (see Part 2).

Now click on the 'Input Parameters' button in the 'Runtime Info' tab.

Look at the 'Output Directory' field within 'Program Directories'.

Now we are ready to load the results into PyMOL: This directory contains all of the results from the ProSMART execution.

There will be five files in this directory: Navigate to the ProSMART output directory, and select 'Output Files -> Superposition -> PDB_files -> 1ryx_A_2d3i_A'.

1ryx_A.pdb - chain A from 1ryx, in its original coordinate frame.

2d3i_A.pdb - chain A from 2d3i, in the global coordinate frame of 1ryx.

1ryx_A_Cluster0.pdb - chain A from 2d3i, with the first substructure superposed.

1ryx_A_Cluster1.pdb - chain A from 2d3i, with the second substructure superposed.

1ryx_A_Cluster2.pdb - chain A from 2d3i, with the third substructure superposed.

Now display all chains using the 'cartoon' representation (in the 'all' object in the bar on the right, select 'S -> as -> cartoon').

To begin with, hide the three 'Cluster' representations by clicking on the respective objects.

This superposition is optimised using all corresponding backbone atoms between the two structures, and thus the superposition is not 'tight' (the superposition is reasonable overall, but is not particularly good anywhere). We will now compare the target (1ryx) and reference (2d3i) structures, looking at domain motion in order to gain intuition regarding differences in their global conformations: However, it is often more useful to have a 'tight' superposition for each of the rigid substructuresР В Р вЂ Р В РІР‚С™Р вЂ™Р’В¦ Viewing Substructure Superpositions - Analysis Of Global Conformational Changes This is as intended, and gives an indication of the overall disagreement between the two structures' global conformations.

The structures now seem better superposed, but it's not that easy to see which bits are superposed and which aren't.

Go to 'File -> Run', and navigate in the ProSMART output directory to 'Output_Files -> Colour Scripts -> 1ryx_A_2d3i_A'.

This directory contains a variety of colour scripts that you can use to colour your structure for various purposes. Run the script 'cluster_0.pml', and wait for PyMOL to process the script. The residues are now coloured according to the similarity of their local coordinate frames. Residues that closely relate to the rigid substructure/cluster are coloured red, gradually fading to white for regions that adopt a noticeably different global conformation.
