Overview

Basic information about this protein and its source genome.

Accession: PA4342
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: PA4342
Status: annotated
Amino acids: 494
Structure source: AlphaFold

GO:0003824 Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.

Target profile

Computed evidence for target prioritization.

Human off-target: hit
Human identity (%): 34.94
Human E-value: 1.42e-28
Gut microbiome off-target: hit
Essential (DEG): N
Localization: Cytoplasmic

Selected Druggability evidence

Selected Druggability is the FPocket score chosen for ranking using the curated structure priority. The 3D viewer may show a different loaded structure, so its visible pockets can differ.

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

55 records

Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.

No PDB structure with a co-crystallized ligand found for this exact protein.

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
