Many pdb-files contain carbohydrate structures. Since there is not such a standard nomenclature like it exists for amino acids, it is difficult to find the carbohydrate information. Sometimes entire oligosaccharides are encoded in one single residue. Information about carbohydrate linkages is often missing, and if it is present, it is not in a unique format and therefore also difficult to find.
pdb2linucs automatically extracts carbohydrate information from pdb-files and displays it using the LINUCS-Code [1] or - translated by LiGraph - the IUPAC-Notation.
