[AMBER] deuterate protein atoms by editing the topology file

Dear Amber users,

I have a solvated system and I want to change the protein hydrogen atoms to
deuterium by just doubling their masses. I have edited the topology file of
the hydrogenated system and doubled the mass of the protein hydrogens under
%FLAG MASS

When I use this new topology file, will sander treat the protein hydrogens
as particles having double mass than the water hydrogens?
