[gmx-users] grompp is adding a bond in my model that should not be there

I made a model of a receptor protein, bilayer, and solvent. My protein
contains a 20 residue gap. This gap corresponds to a region of the protein
that had been digested by trypsin before crystallization. The trypsin
digestion has no affect on receptor activity experimentally. I performed
energy minimization without problem. The protein looked like it should,
containing the gap.
When I performed equilibration, the output had the C-terminus of one
protein fragment connected to the N-terminus of the other protein fragment.
I don't know how this peptide bond was created, because it was not in the
input *.gro file to grompp. Please help.
