I have worked extensively on GAGS in particular heparin. You may wish to
refer to my publications.
Glycam has residues for sulphated glucuronic acid/iduronic acid as well as
sulphated glucosamine. You can build topologies for heparin using glycam
webserver. If you wish to run your simulation in GROMACS, you can convert
glycam amber topologies to gromacs format using Acpype.
There are no direct parameters in GROMOS force fields to build sulfated
GAGs (although parameters exist for hexapyranoses). Hugo Verli has used
GROMOS force fields to simulate heparin oligosaccharide. Kindly refer to
his publications for parameters for GAGs.
CHARMM has parameters for GAGs like CS, DS but they lack parameters for
N-sulfated glucosamine. You can use Charmm-gui to obtain parameters.
I hope this helps,
