Atom completeness · selected chain and annotation core
What can these coordinates support?
A fully observed annotation core is not a complete-receptor certification. Short annotation intervals, absent peripheral residues, alternate conformers and unexamined density can limit structural interpretation. No receptor preparation was performed.
Frozen 5 Å heavy-atom proximity observations
Contacting residues · SO4
Heavy-atom distances use the first deposited model and asymmetric unit, occupancy >0 and retained alternate locations. No symmetry expansion or affinity inference. Proximity alone is not evidence of affinity or a functional interaction.

Source bytes, methods and provenance
Detailed atom completeness only for the three packaged original-coordinate files; quality uses observed atom-name union across positive-occupancy alternate conformers, with per-alt differences retained. Missing entire residues are separate. Nonstandard amino-acid templates are unassessed. No density reinterpretation, receptor repair, docking or MD.
