Can I use heme prameters with param94 ?



Dear CCLers,
 I have performed MD simulations with AMBER param94 and db94. Because my
 system has been constituted by only a protein and solvent water, everything
 has been O.K.. But now, I must treat a system which includes a heme-protein.
 I want to continue using param94 and db94 because I want to use neutral-Asp
 and neutral-Glu.
 My question is whether can I use the all-atom heme parameter set (heme-all.
 in and frcmod.hemall) that is on the AMBER home-page with param94 and
 db94 ? If some modifications are required, do someone has any information
 about them ?
 Any information will be appreciated.
 Best regards,
 Kazuki
