Building molecules using Peptide Model Kit
This model kit allows you to build peptides using the 20 amino acids found in
proteins. You can choose the conformation of your peptide sequence and the bond
angles. Be cautious with the length of you sequence because the
long it is the more time it will take to do the energy calculations. In the
Advanced Spartan tutorial we will go over how to run these calculations in the
background while you continue to work on other projects.
In the builder:
Click on the Peptide button at the top of the model kit.
Click on the conformation you prefer - alpha helix, beta sheet, or other.
The other selection lets you enter your own phi and psi angles.
Click the Build Sequence check box.
Click on the button of the first amino acid of your sequence, and then the
second, extra, extra.
You can see the sequence in the text box, under the Build Sequence check box.
Click on your workspace to see the peptide.
Select the charged or uncharged amino and carboxyl group that you want to
have on the terminal ends of your peptide.
Click on the terminate box.
Now you can minimize your peptide, save it, and view it in the main window.
NOTE: I do not know how to zoom out in the main window. If you figure it out
PLEASE let me know.
