Such as protein conformation can be described by the backbone torsion angles,
a carbohydrate structure is mainly characterised by its linkage torsions.
With the aid of pdb2linucs, a dataset of
carbohydrate torsion angles was derived from from carbohydrate structures
found in the PDB.
This weekly updated dataset contains, besides linkage torsions, also ring
torsions, omega torsions, N-acetyle group torsions and sidechain torsions of
Asn residues involved in Glycan bonds. It can be queried by
The same data is used by carp
to generate PDB-derived plot backgrounds.
