Lubos Vrbka" [lubos.vrbka- -uochb.cas.cz] hi, > I am novice user here and would like to do some molecular dynamics calculation of an enzyme, with special requirement that only heating a part of the protein and freeze the rest. i.e., after minimizing and equilibrating the whole protein at 10K, only thermalize the active site of the enzyme to 300K. > > I am wondering which MD package could that. If possible, I prefer to free software such as TINKER. i think gromacs should be able to do that... and it is for free (GPL, iirc) as well. regards, lubos -- .....................................................
