  • GO:1902600 The directed movement of a proton across a membrane.
  • 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:0008746 OBSOLETE. Catalysis of the reaction: NADPH + H+ + NAD+ = NADP+ + NADH + H+.
  • GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
  • GO:0050661 Binding to nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NADP+, or the reduced form, NADPH.
  • GO:0008750 Catalysis of the reaction: H+(in) + NAD+ + NADPH = H+(out) + NADH + NADP+.
  • GO:0006740 A metabolic process that generates a pool of NADPH by the reduction of NADP+.

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.

60 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.
