[Chimera-users] Protonating ASP and GLU

[Francesco Pietra]

Is there any special reason why, in the AddH option, side chains are
only considered for HIS (with full options)? Why similar options are
not given to protonate GLU and/or ASP at the carboxylate?

The general option to consider H-bonding does not work in my case for
such residues close to one another in space with Chimera (the two O
atoms of two ASP residues are at 2.56A from one another). Even Reduce,
supposed to protonate close lying carboxylates, failed in my case.
This is why I would consider to add that option in future versions of
Chimera.

Thanks
