Dear Dr. Thomas Steinbrecher
I read amber - tutorial a9 (from atila petrosian) in amber mailing list.
I want to do relative binding free energy analysis for my system
(protein-dna comlex).
In my case, ligand is dna. I will investigate mutation of the dna (for
example, T ---> G). My thermodynamic cycle is as follows:
mdna = mutated dna
delta G1
Protein-dna ----- protein-mdna
delta G3 | | delta G4
dna ----- mdna
delta G2
I want to calculate delta delta G = delta G2 - delta G1 = delta G4 - delta
G3
You broken up each transformation into three substeps : 1) Remove charges
from BNZ 2) Transform BNZ into PHN and 3) Add charges to PHN.
I want to know should I use 3 substeps also?
thanks
