  • GO:0003957 Catalysis of the reaction: NADPH + NAD+ = NADP+ + NADH.
  • GO:0016491 Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
  • GO:0050660 Binding to FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
  • GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
  • GO:0004148 Catalysis of the reaction: N(6)-[(R)-dihydrolipoyl]-L-lysyl-[protein] + NAD+ = N(6)-[(R)-lipoyl]-L-lysyl-[protein] + NADH + H+.
  • GO:0006103 The chemical reactions and pathways involving oxoglutarate, the dianion of 2-oxoglutaric acid. It is a key constituent of the TCA cycle and a key intermediate in amino-acid metabolism.
  • GO:0006739 The chemical reactions and pathways involving nicotinamide adenine dinucleotide phosphate (NADP+), a coenzyme that interconverts with its reduced form, NADPH, in many redox and biosynthetic reactions.

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.

66 records

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.
