[gmx-users] addition of an isopeptide bond and its simulation

[Raag Saluja]

Hi!

 I need to study the effect of post-translational modifications on the
biophysical properties of my protein. This involves the addition of an
isopeptide bond to the primary chain of the C-terminal tail.

How may I add this isopeptide bond? And then which force field can I use to
simulate it?

Looking forward to your kind help!
Regards,
