540 Cytochrome c oxidase subunit h
Ligands and drugs
Aggregated over all current member domains of this group. Drug annotations come from DrugDomain; buffers and crystallization additives are excluded from the tables below.
Chemical profile
ClassyFire chemical superclasses of the ligands bound by this X-group's proteins, from DrugDomain annotations.
The raw number of superclasses rises with the number of proteins sampled; the per-20 value compares X-groups at equal depth.
| Superclass | Proteins | Expected | 0.25×observed / expected4× | Ratio | Significance |
|---|---|---|---|---|---|
| Hydrocarbons | 1 | 0.0 | 73× | not tested | |
| Lipids and lipid-like molecules | 2 | 0.2 | 9.11× | not tested | |
| Homogeneous metal compounds | 1 | 1.0 | 1.03× | not tested |
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.
