Coincidentally, I just noticed this problem while perusing a
validation report last night and am tooling up to see if I can get this
problem fixed.
The origin of the flaw is the asymmetry of the NH1 and NH2 atoms in
Arginine. If one considers only bonding it would appear that these two
Dear crystallographers,
Lately when refining a structure (at 2.8A) with Refmac5 I've found that nearly
all Arg residues get distorted at one angle: NE-CZ-NH1(2). Starting model has
120*, final model 123*(117*), which validation server considers a major issue.
May any of you recognize why is
