Press enter.

Change the display of the structure to ball and stick.


On the command line, type,

rep bs

Change the ball scale value to 0.5.


On the attributes dialog box, change the Van der Walls radii of the atoms.

Change the value of ball scale to 0.5.

Press Enter.

Cursor on the panel. Observe the panel. The atoms are shown with larger atomic radii.
Click on Atom Attributes. Again click on Molecular Attributes check box.

From the list, click on Component Atom Attributes.

Select sphere. In the corresponding window, click on atom style button .

The drop-down menu has many options.

Click on sphere to change the display to cpk.

Observe the panel.

Select dot to bring back the sticks display.

Click on Component Bond Attributes. Now click on Component Bond Attributes.

Here, there are options to change bond style to stick or wire.

Click on Component Residue Attributes. Click on Component Residue Attributes.

Here we have options to change the attributes of the ribbon.

Click on Presets menu, change the display to ribbons. Using presets menu, change the display of the structure on the panel to ribbons.
Click on the color well.

Choose a color from the color editor dialog box.

Close the color editor dialog box.

Now, click in the Attribute dialog box,

Now,in the Attribute dialog-box, click on the color well next to ribbon color.

Click on atoms from the Attributes drop-down.

Here we have options to change the attributes of atoms, residues, molecules, segmentation regions etc.

Select atoms.


Click on Render.

Click on the the Attribute list. Click on Attribute list to check for available options.


The list shows two options: bfactor and occupancy


These two attributes can be read from the input PDB file.

Select bfactor.


Cursor on the Histogram.

Choose bfactor.


A histogram of values will appear, with colored vertical bars.

Slide Number 6

B-factor

  • B-factor values are a measure of mobility in the macromolecule.
  • Atoms with low B-factor values belong to a part of the structure that is well ordered.
  • Atoms with large B-factor values belong to part of the structure that is very flexible.
Slide Number 7

B-factor

PDB file for a protein structure contains B-factor information.

  • kdHydrophobicity scales are values that define relative hydrophobicity of amino acid residues.
  • KdHydrophobicity values are positive for hydrophobic residues and Negative values for polar residues.
Cursor on the panel. Hydrophobicity of the residues can be shown with colors or worms.


Choose Colors. By default, some of the parameters are selected.


Click on Apply button. Observe the panel.


The hydrophobic residues are colored in red, and polar residues are colored in blue.

Click on Worms button.


Click on apply.

Click on Worms button. Click on Apply.

Observe the panel.

Worms are modified ribbons that vary in radius.
