Superclasses per 20 proteins
narrower than 81% of the 256 X-groups with enough proteins to compare (median 7.6)
The raw number of superclasses rises with the number of proteins sampled; the per-20 value compares X-groups at equal depth.

Unit: a protein (UniProt accession) with a ligand-binding domain in this X-group, counted once per superclass. Expected counts use each superclass's frequency across all ligand-binding X-groups; significance is Fisher's exact test with Benjamini–Hochberg correction. Buffers and crystallization additives are excluded. ECOD v295.2; the method follows the ECOD 2027 update, whose published figures used a slightly different artifact filter.
