4995 Methionine synthase domain-like
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 |
|---|---|---|---|---|---|
| Organoheterocyclic compounds | 4 | 0.8 | 5.27× | not tested | |
| Homogeneous non-metal compounds | 3 | 1.1 | 2.83× | not tested | |
| Lipids and lipid-like molecules | 1 | 0.6 | 1.82× | not tested | |
| Nucleosides, nucleotides, and analogues | 1 | 1.4 | 0.73× | 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.
