Dear all,
We are attempting some MMGBSA calculations on a protein-nucleic acid
complex and we'd like to get some feed-back on the generalized born
parameters.
For the record, we are using ff99SB/ildn/nmr force field variant.
I know that generally igb=1 has been tested and recommended on nucleic
acids. According to the original work by Vickei Tsui and Dave Case,
igb=1 + mbondi radii with the parameter changes highlighted in the
AmberTools manual is the preferred combination for nucleic acids.
I also know that for proteins igb=5 and the new igb=7 and igb=8 +
mbondi2 are performing better.
My question is: what about state-of-the-art for protein-nucleic acid
complexes ? Is anybody willing to share some latest experiences and some
new relevant references about the choice of parameters ?
Thanks for any insights,
Best wishes
Vlad
