Overview

Basic information about this protein and its source genome.

Accession: VK055_3981
Assembly: Klebsiella pneumoniae subsp. pneumoniae strain ATCC 43816 KPPR1, complete genome
Gene: AIK82529.1 dhaB
Status: annotated
Amino acids: 555
Structure source: Experimental + ColabFold

4.2.1.30

GO:0031419 Binding to cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom. 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:0016836 Catalysis of the cleavage of a carbon-oxygen bond by elimination of water. GO:0046405 Catalysis of the reaction: glycerol = 3-hydroxypropanal + H2O.

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.

51 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.
