GO:0005524 Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. GO:0008817 Catalysis of the reaction: 2 ATP + 2 corrinoid + reduced [electron-transfer flavoprotein] = 2 adenosylcorrinoid + 3 H+ + oxidized [electron-transfer flavoprotein] + 2 triphosphate. The corrinoid can be cob(II)yrinate a,c diamide, cob(II)inamide or cob(II)alamin. GO:0009236 The chemical reactions and pathways resulting in the formation of cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom.

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.

52 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.
