 Dear Mark

 Thanks for your answer.

 I have a pdb file. If I want to cap N- and C-terminal with ACE and NME,
 respectively, what to do? Is there an specific software for that?

 Best wishes,
 Shahab

[gmx-users] residues in force fields

2015-01-31 Thread shahab shariati
Dear all

I am a beginner in gromacs. I am studying manual and force fields.

I have a question about 2 residue name in aminoacid.rtp file in force
fields (for example, amber03).

I want to know ACE and NME residues.

Any help will highly appreciated.

Hi,

Those are for acetyl and N-methylamine chemical moieties. Those are often
used to cap peptide fragments to avoid zwitterions (both in simulation and
experiment).
