Promising target candidate with multiple supporting evidence streams.
Automated synthesis of the evidence currently loaded. Review the underlying records before prioritizing this protein.
Main supporting evidence
Terms and data sources used on this page
PDB: experimentally determined structures from the Protein Data Bank. These are the strongest structural evidence, but may cover only part of the protein.
AlphaFold DB model: a precomputed predicted structure downloaded from AlphaFold Database/UniProt, not an experiment performed here.
ColabFold model: a predicted structure generated for this workspace; interpret it with coverage and confidence.
pLDDT: confidence score for predicted structures. High values support local geometry; low values mean the region should not drive pocket interpretation.
FPocket / P2Rank: software tools that predict possible ligand-binding pockets on a 3D structure. They are useful screening signals, not experimental validation.
Druggability: a pocket-based estimate of whether a small molecule could bind productively. It does not mean a drug already exists.
PDB ligand: a compound observed in an experimental structure. Direct same-protein records are stronger than homolog-transferred records.
ChEMBL: a public database of measured compound bioactivity. Direct entries are stronger than entries transferred from similar proteins.
ZINC: a purchasable-compound database. Here it marks proposed candidates from chemical similarity, not measured binders.
LigQ / LigQ_2: an internal Target pipeline step that gathers PDB, ChEMBL, and ZINC ligand evidence for each protein.
Off-target: sequence similarity to proteins we prefer not to hit, such as human proteins or beneficial gut microbiome proteins.
DEG: Database of Essential Genes. A match suggests the protein resembles genes known to be essential in other organisms.
Roary / CoreCruncher: pan-genome tools used to decide whether a gene is core across analyzed strains or accessory/strain-specific.
EC / GO: functional annotations: EC describes enzyme reactions; GO describes biological process, molecular function, or cellular component.
KEGG pathway: a curated metabolic route label used here to group reactions imported from the metabolic model.
Chokepoint: a metabolic reaction that is the only producer or consumer of a metabolite in the imported model.
Prioritization evidence
Selectivity, essentiality, structural confidence, conservation, and predicted binding-site evidence.
Off-target risk
- Human off-target
- No hit
- Gut microbiome similarity
- 1.1% of screened genomes Lower prevalence suggests narrower overlap with the screened gut microbiome.
Essentiality
- Essential (DEG)
- Y
- DEG identity (%)
- 52.906 Higher values support similarity to known essential genes.
- DEG E-value
- 0.0 Smaller values mean stronger essential-gene similarity.
Structure confidence
- ColabFold pLDDT
- 93.84 0-100 confidence; >70 supports local structural interpretation.
Binding-site evidence
AlphaFold DB / UniProt modelP2Rank's binding-site probability is the primary druggability signal shown across the app; FPocket's druggability score is shown alongside it for comparison. Both estimate small-molecule pocket quality after applying the curated structure priority — neither is experimental binding evidence. The 3D viewer may show a different loaded structure, so visible pockets can differ.

PDB and ChEMBL records on this protein are shown in full. ChEMBL records from similar proteins are capped at the top 100 per protein (by pchembl) and ZINC at the top 50 (Tanimoto ≥ 0.5). ADME columns are descriptor-based screening flags, not experimental toxicity results.
