Hi All!
I have performed the molecular dynamic for 9ns of protein in 2M and 6M Urea solutions. The literature data estimate the values of secondary structure (b-sheet) as 80-90% and 0%-10% repetitively. But measured values from this dynamic are 85% and 80%. Is anybody having any ideas about this error? I have used GROMOS96FF with urea topology from gromacs suit. The starting structure was taken from crystal data.
Thank you.
