Dear discussion board,
I'm trying to get a homology model of a GPCR using I-TASSER.
I know for sure that there is a disulfide bond between two cysteine residues (161 and 173), but the prediction server doesn't seem to respect the restraints I give him (attached in this post).
I've tried various methods to try to force the two sulfur atoms together:
Am I missing something?
Thank you in advance,
Marco
