The residues labelled UNK 801 through 811 represent residues whose electron density is robust enough only to trace the main chain. It is not clear how these atoms correspond to the sequence assignment. The CA atoms are intended to communicate the fact that there is significant density (visible at 0.6 sigma or lower) in the region of the active site that is very near to the bound cofactor analog and therefore potentially making interactions with the analog.
