Unfortunately, the structure and associated paper for PDB id 2hr0 has _not_ been retracted, or marked as invalid.
The University of Alabama had a note about it, but only some of the affected PDB entries were removed. http://www.uab.edu/reporterarchive/71570-uab-statement-on-protein-data-bank-issues For 2hr0, the Nature letter ( http://www.nature.com/nature/journal/v444/n7116/full/nature05258.html) and the associated structure has not been removed from the archives.
