The black crosses on the secondary structure diagrams indicate where the PDB and UniProt sequences differ.

Where there is more than one PDB model for a given UniProt sequence, the models are ordered by: 1. decreasing order of similarity to the UniProt sequence, 2. X-ray structures (in order of increasing resolution), NMR structures, and theoretical models. Clicking on any PDB code take you to the corresponding PDBsum page.
