You might try PCMODEL available as a shareware program.

there are some real possibilities, but software is needed
to convert the Brookhaven to PCMODEL format.  There is a hint
that this program is available on registration ($70.00).
  The main problem with
the Brookhaven format is that PCMODEL requries a connect table.
One would also like the possibility of showing only the alpha
carbon backbone.  This could also be done with the proper manipulation
of the Brookhaven format.  I have tried this on a 486 and
it flies.

there is another commercial program from hyperchem.  This has
been advertised in Science.  It looks very powerful--lets you
do molecular dynamics calculations, etc.  But the price is rather steep.
