Overview

Basic information about this protein and its source genome.

Accession: PA3767
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: tadA PA3767
Status: annotated
Amino acids: 182
Structure source: AlphaFold

3.5.4.33

GO:0052717 Catalysis of the reaction: adenosine34 in tRNA + H2O + H+ = inosine34 in tRNA + NH4+. GO:0008270 Binding to a zinc ion (Zn). GO:0002100 The process in which an adenosine at position 34 of a tRNA is post-transcriptionally converted to inosine. The wobble nucleoside of the tRNA sequence (position 34) corresponds to the first position of the anticodon. GO:0016787 Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. 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. GO:0008251 Catalysis of the reaction: adenosine + H2O = inosine + NH4+, in a tRNA molecule.

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.

62 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.

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.
