The chemical reactions and pathways involving nicotinamide nucleotides, any nucleotide that contains combined nicotinate (pyridine 3-carboxylic acid, or niacin).

The chemical reactions and pathways resulting in the formation of a pyridine nucleotide, a nucleotide characterized by a pyridine derivative as a nitrogen base.

A protein deubiquitination process in which a K6-linked ubiquitin chain, i.e. a polymer of ubiquitin formed by linkages between lysine residues at position 6 of the ubiquitin monomers, is removed from a protein.

The removal of one or more ubiquitin groups from a protein.

The generation of nicotinate nucleotide without de novo synthesis.

Any process that generates a pyridine nucleotide, a nucleotide characterized by a pyridine derivative as a nitrogen base, from derivatives of them without de novo synthesis.

A protein ubiquitination process in which a polymer of ubiquitin, formed by linkages between lysine residues at position 27 of the ubiquitin monomers, is added to a protein.

Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain.

An oligosaccharyltransferase (OST) complex that contains at least seven polypeptides and is the major OST complex in mammalian cells. Of the three forms of mammalian OST complex identified, the OSTI complex has the weakest affinity for ribosomes.

A protein complex that is found in the endoplasmic reticulum membrane of eukaryotes and transfers lipid-linked oligosaccharide precursor to asparagine residues on nascent proteins. In yeast, the complex includes at least nine different subunits, whereas in mammalian cells at least three different forms of the complex have been detected.

An oligosaccharyltransferase (OST) complex that contains the seven polypeptides found in OST complex I, plus heterotrimeric Sec61alpha-beta-gamma. Of the three forms of mammalian OST complexes identified, the OSTII complex has intermediate affinity for ribosomes.

A protein complex that contains CREB and FHL3, and is involved in transcriptional regulation.

A protein complex that possesses DNA helicase activity.

The peptide cleavage of mitochondrial proteins, including cleavage contributing to their import.

Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a protein. Protein maturation is the process leading to the attainment of the full functional capacity of a protein.

A protein complex that contains CREB and FHL2, and is involved in transcriptional regulation.

Any large protein complex that contains Ecsit and NDUFAF1, is located in the mitochondrion, and is involved in the assembly of complex I of the oxidative phosphorylation system. In mammalian cells, three complexes of approximately 500, 600, and 850 kDa containing the 45 kDa isoform of Ecsit and NDUFAF1 have been observed.

Directly binding to and delivering iron ions to a target protein.

Binding to and delivering metal ions to a target protein.

The removal of an acetyl group from an acetylated lysine residue in a peptide or protein.
