[gmx-users] gramicidin A

[David L. Bostick]

I am interested in simulating the HD form of gramicidin.  I started looking
into building the topology, but decided to look around first.  It seems
that it has already been simulated using GROMACS:

Biophys J Vol 82, June 2002 pp. 2934-2924

by de Groot, Tieleman, Pohl, and Grubmuller.  The abberant parts of the
topology are at the termini.  There is a formyl group on one end and an
ethanolamine group on the other.

Is there a set of building block files out there with these residues
included ... or even a topology of a single monomer of GA?  I can just dig
in myself, but I thought I'd ask around first ... it doesn't hurt to ask.

Thanks,
David
