Re: [gmx-users] protein constrained, ligand ot constrained

2007-04-15 Thread Lars . Schaefer
hi Luca, I dont quite understand your point. The benefit of constraints is that they allow you to use a larger timestep of, say, 2 fs instead of 1 fs or so. But if you dont constrain your ligand, you have to use a small timestep anyway, so there is no reason to constrain the protein then. BTW: acco

I have now programmed in the conserved quantity (not committed yet). SPC water gives the same energy conservation in NVT Nose-Hoover as in NVE. I did a run of 100 ps for 216 SPC with dt=0.002 ps and SETTLE at 300 K, tau_t=2 ps: NVE: drift per degree of freedom -0.026 kJ/mol /ns NVT: drift per degr

[gmx-users] protein constrained, ligand ot constrained

2007-04-15 Thread mollica.luca
Dear all, I would like to set up a simulation of a protein-ligand system with the protein left bond-constrained using LINCS algorithm and the ligand left unconstrained, i.e. in order to check the effect of some variations of force constants that I have computed on the protein-ligand interactions.

[gmx-users] QM/MM investigate phosphorylation/dephosphorylation in kinase

2007-04-15 Thread Qiang Zhong
Dear all: I am preparing search reaction path in kinase by QM/MM, The kinase is a kind of autophosphorylation/autodephosphorylation enzyme , I have search many paper, but I have not find similar paper, Could somebody tell some similar paper, or give me some advice? Thank you very much!
