[gmx-users] Cytochrom C

[Peter C. Lai]

Btw if you want a CHARMM27 version you should be able to parameterize it 
from the existing atomtypes like (not verified) (adapted from ALA):

[ ACE ]
 [ atoms ]
   CH3	    CT3    -0.27    0
   HH31     HA      0.09    1
   HH32     HA      0.09    2
   HH33     HA      0.09    3
   C        C       0.51    4
   O        O      -0.51    5
 [ bonds ]
   CH3    H1
   CH3    H2
   CH3    H3
   CH3    C
   C      O

Surprisingly, an .hdb entry for ACE exists so you don't need to create one.
