[Chimera-users] bond formation

[Elaine Meng]

Hi Arthur,
If you just mean to draw a bond and not move anything, if the atoms are already selected you could just use command:  bond sel

There is also a graphical interface, Tools… Structure Editing… Build Structure, the Adjust Bonds section.

I hope this helps,
Elaine

The model number  is the same for the two chains designated A and B. I have looked through the various tutorials, functions and tools to figure out how to actually place a bond between two residues that link the two chains. It is well established as to how the two proteins would be linked if the bond had been formed.
