Dear GLYCAM users,

I would like to simulate several galactose derivatives bound to a protein. I would like to proceed with a QM parametrization by using gaussian to optimize the geometry and calculate the ESP and then use the AMBER tools to fit resp charges and generate the parameter sets for simulating with the AMBER ff.

Shall I parametrize the entire molecule or just the aglycon portion and use the GLYCAM parameters for the galactose moiety? If the latter is the best option, how can I parametrize the aglycon with a 'reacting' end to be then attached to the standard galactose moiety?

I tried to look if anybody asked the same question before, but I could not find any hints.

Thanks for your time and help,
