Statistical data

Statistics of the data in Danish (last update of the data: 2026-10-15). See Data in Danish for how the data are prepared.

Cumulative number of PDB entries

By deposition year.

Oligomeric count

Number of PDB entries by the number of chains in the first biological assembly.

Resolution

Number of PDB entries by resolution (626 entries without a resolution, e.g. NMR, are not shown).

Missing residues and structural gaps by resolution

Number of PDB entries with missing residues or structural gaps (in every assembly of the entry), by resolution. The table also gives all entries of each resolution range and, in parentheses, the percentage of them.

Experimental methods

Number of PDB entries by experimental method.

Axial ligands

Number of hemes by the combination of axial ligands (the 12 most frequent; "None": no axial ligand).

Note: these statistics are computed over all data in Danish; redundancy of amino-acid sequences (e.g. many structures of the same protein or of its mutants) is not removed. The statistics are recalculated from the database whenever the data are updated.
