Accession: PA4744
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: infB PA4744
Status: annotated
Amino acids: 840
Structure source: AlphaFold

GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. GO:0005525 Binding to GTP, guanosine triphosphate. GO:0003924 Catalysis of the reaction: GTP + H2O = GDP + H+ + phosphate. GO:0003743 Functions in the initiation of ribosome-mediated translation of mRNA into a polypeptide. GO:0006413 The process preceding formation of the peptide bond between the first two amino acids of a protein. This includes the formation of a complex of the ribosome, mRNA or circRNA, and an initiation complex that contains the first aminoacyl-tRNA.

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.

61 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.
