  • GO:0036055 Catalysis of the reaction: N(6)-succinyl-L-lysyl-[protein] + NAD+ + H2O = 2''-O-succinyl-ADP-D-ribose + nicotinamide + L-lysyl-[protein].
  • GO:0036054 Catalysis of the reaction: N(6)-malonyl-L-lysyl-[protein] + NAD+ + H2O = 2''-O-malonyl-ADP-D-ribose + nicotinamide + L-lysyl-[protein].
  • GO:0070403 Binding to the oxidized form, NAD, of nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions.
  • GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
  • GO:0017136 Catalysis of the reaction: N(6)-acetyl-L-lysyl-[histone] + NAD+ + H2O = L-lysyl-[protein] + 2''-O-acetyl-ADP-D-ribose + nicotinamide. This reaction transfers an acetyl group from a histone to NAD, producing nicotinamide.

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.

156 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.
