Q

Why is molecular dynamics important?

A
Dynamical properties of proteins key elements in;
Conformational enzyme changes 
Molecular motors 
Protein folding 
PPIs 
Allosteric protein regulation 
Membrane transport.

Q

Give an example of how MD simulations have aided drug discovery efforts.

A

p53 - experimental structures have occluded a dynamic binding pocket.
This pocket on surface of p53 is a potential target to reactivate p53 cancer-related mutants.

Q

what is explicit salvation model?

A

Water molecules explicitly included in simulated system.
Accurately describe specific solvent-solute interactions
But expensive as Nwat^2 calculations
