[gmx-users] Glycoproteion MD

[Laercio Pol Fachin]

Hi,

If you can't find parameters for glycoprotein's MD for charmm27, OPLS or Amber99 (and GROMOS is an alternative for you), we've been working on MD simulations with this class of biomolecules, using GROMOS96 43A1 force field, as described:

Pol-Fachin, L.; Fernandes, C.L.; Verli, H.: GROMOS96 43a1 performance on the characterization of glycoprotein conformational ensembles through molecular dynamics simulations. Carbohydrate Research 344 (2009) 491–500.
Fernandes, C.L.; Sachett, L.G.; Pol-Fachin, L.; Verli, H.: GROMOS96 43a1 performance in predicting oligosaccharide conformational ensembles within glycoproteins. Carbohydrate Research 345 (2010) 663–671.

Best regards,
Laércio Pol-Fachin

If they haven't already been derived (and thus likely published), then you'll 
have to derive them yourself in a manner consistent with the original force field.
