Hi,

I have two questions that may seem quite simple, but I haven't found clear answers to them. It has to do with the md simulation parameters of a solvated protein/membrane system.

The first question is about temperature. Some papers simulate at 300 K, others at 298 K, and others at physiological temperature (310 K). I decided that simulating at 310 K gives the most "realistic" picture of the system, as that is biological temp. Why do many studies use 300 K? Is it incorrect to use 310 K for this system? The goal of my work is solely to simulate a GPCR and perform virtual screening on it.

I also decided to simulate the system at physiological salt concentration (.15 M [NaCl]). Will this alter the conformation of my protein significantly?

Thanks,
