Overview

Basic information about this protein and its source genome.

Accession: KP13_04676
Assembly: Klebsiella pneumoniae subsp. pneumoniae Kp13, complete sequence
Gene: AHE44064.1 infC
Status: annotated
Amino acids: 144
Structure source: AlphaFold + ColabFold

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. GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0043022 Binding to a ribosome. GO:0032790 The disaggregation of a ribosome into its constituent components; includes the dissociation of ribosomal subunits.

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.

53 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.
