[gmx-users] Protein Structure Prediction

[Steven Neumann]

Thank you Emanuel. I will try what you have suggested and I think I will
try to confirm it exeprimentally to be sure about my initial structure.
This is terminal which is highly flexible and beta loops are very common
for this sequence.
Thanks a lot!
