Dear all,
I want to construct the structure of Ala3 peptide shown as follows using AMBER12 package with Amber99SB force field.
I have tried to use the sequence {NALA ALA CALA } in the tleap, but I failed.
Because I must keep the N-terminus of the peptide be protonated, the C-terminus be neutralized.
How do I get it?
Please help me in this regard in brief.
Thank you very much !
