[gmx-users] ATP parametrization

[Bjoern Windshuegel]

hi guys,

i'm trying to parametrize some ligands for my simulations. since i have a
phosphate group in one ligand i tried to use the parametrization as it is
done for ATP in ffG43a1.rtp. for the dihedrals there are some puzzling
parameters:
 
 AC5* AO5*  APA   AO3PA   gd_11
 AC5* AO5*  APA   AO3PA   gd_9

is there any intelligent reason why both dihedrals were chosen? gd_9 as
well as gd_11 are suited but both together...???? 

best regards,

bjoern
