Hi Mark, I just want to look into the conformational change of the enzyme after reduction of the co-factor FAD. So instead of feed into a reducing molecule and do some complicated QM simulation, I wonder if this way would be better. I understand that this is not physical.
But what could be an alternative way to look at the system evolution upon reduction of the co-factor?
