Hi all,  
 
I'm performing simulations on peptides containing 
cystaine residues as they are, but I would like to 
try simulating the same peptides when the cysteine 
residues are protected by (for example) an 
acetamidomethyl group. Unfortunately there are 
some missing parameters in the parm99 force field, 
regarding the angle bending terms involving the S 
atom. Is there any parameter avaible somewhere for 
this situation, and what atom tipe schould I chose 
for the S atom? Antechamber suggestes the S atom 
tipe, and it seems to make sense. 
 
Thank you in advance 
 
Stefano Pieraccini
