you can do this with several programs, for instance
with O
however, i wouldn't trust the side chain atoms,
so i wouldn't generate more than a poly-ala model
if i were you for mol replacement calcns (every
atom in the wrong place adds to the noise)

as an aside, i recently had a look at 88 CA-only entries
in the PDB and found that almost a dozen of these are
suspicious (including some of the cases of which we
already know that they are wrong, like 1PHY);
if you mail me with the pdb id of the structure you
want to use, i'll let you know what i think of it
