So the easiest way of having multiple chains would be to just have a
single pdb file with the multiple chains? Would you happen to know of a
single pdb file with multiple chains (something I could grab off the pdb
site) I could use as a reference?
This depends entirely upon what your goal is. Your original question implied
you wished to build a system of multiple, identical peptides, pertaining to:
http://www.gromacs.org/Documentation/How-tos/Multiple_Chains#Identical_chains
Now you want a multimeric protein for which there are multiple, potentially
different peptide, i.e.:
http://www.gromacs.org/Documentation/How-tos/Multiple_Chains#Non-identical_chains
The approaches are completely different, as the documentation should make quite
clear. Simply "having multiple chains" is a very vague statement. Perhaps if
you clearly stated your goal for the simulation I (or someone else) could help
you better.
As for the PDB site, there are probably thousands of proteins in line with what
you want. Any heteromultimeric protein would do (assuming, of course, the
latter case of non-identical chains).
