<br>
Can I please vote in favor of having torsion and chirality
restraints added to the monomer library for NAG-ASN links?
BETA1-4, etc. have them, why not NAG-ASN? Something like CNS has
for the equivalent B1N in "carbohydrate.top". This would really
help those of us cursed with glycosylation, and would make our
unfortunate lives wee bit easier.<br>
<br>
Cheers,<br>

<div>Supply this file to phenix.refine to retain the chiral. I
have been debating adding this to the GeoStd so if it works
I'd like to see the result and maybe add it.</div>

everyone,<br>
<br>
I am refining a glycoprotein model, and I have applied
NAG-ASN link to the ASN. But the beta-conformation of NAG
could not be retained after refinement for some sites. I
read the cif file and find that there are only angle
definitions for NAG-ASN. The dihedral and charility
information are missing. Is there a way that I could retain
the charility of C1 of NAG?<br>
<br>
Thank you!<br>
