The sialoglycopeptide from glycophorin A (chain D of PDB entry 2cwg; Wright & Jaeger, 1993) required multiple reannotation events: a LINK record was added to connect the threonine side chain to the central carbohydrate residue, the central residue NDG was renamed A2G (α-D-GalpNAc) and a LINK record between GAL and A2G was rewritten to correctly describe the leaving atom O1. The dotted line represents a glycosidic linkage that was already present in the PDB entry but is not displayed by CCP4mg. |
