1168 MERS-CoV helicase helical bundle domain
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 |
|---|---|---|---|---|---|
| Benzenoids | 1 | 0.1 | 6.94× | not tested | |
| Organoheterocyclic compounds | 1 | 0.3 | 3.29× | not tested | |
| Organic acids and derivatives | 1 | 0.3 | 3.28× | not tested | |
| Homogeneous metal compounds | 2 | 1.0 | 2.07× | 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.
