Chain A,B,C,D   (NPT1_YEAST | P39683)
molecular function
    GO:0016874    ligase activity    Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate.
    GO:0004516    nicotinate phosphoribosyltransferase activity    Catalysis of the reaction: diphosphate + nicotinate D-ribonucleotide = 5-phospho-alpha-D-ribose 1-diphosphate + H(+) + nicotinate.
    GO:0004514    nicotinate-nucleotide diphosphorylase (carboxylating) activity    Catalysis of the reaction: CO(2) + diphosphate + nicotinate D-ribonucleotide = 5-phospho-alpha-D-ribose 1-diphosphate + 2 H(+) + quinolinate.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0009435    NAD biosynthetic process    The chemical reactions and pathways resulting in the formation of nicotinamide adenine dinucleotide, a coenzyme present in most living cells and derived from the B vitamin nicotinic acid; biosynthesis may be of either the oxidized form, NAD, or the reduced form, NADH.
    GO:0000183    chromatin silencing at rDNA    Repression of transcription of ribosomal DNA by altering the structure of chromatin.
    GO:0006348    chromatin silencing at telomere    Repression of transcription of telomeric DNA by altering the structure of chromatin.
    GO:0019357    nicotinate nucleotide biosynthetic process    The chemical reactions and pathways resulting in the formation of nicotinamide nucleotides, any nucleotide that contains combined nicotinate (pyridine 3-carboxylic acid).
    GO:0019358    nicotinate nucleotide salvage    The generation of nicotinate nucleotide without de novo synthesis.
    GO:0019363    pyridine nucleotide biosynthetic process    The chemical reactions and pathways resulting in the formation of a pyridine nucleotide, a nucleotide characterized by a pyridine derivative as a nitrogen base.
    GO:0001302    replicative cell aging    The process associated with progression of the cell from its inception to the end of its lifespan that occurs as the cell continues cycles of growth and division.
cellular component
    GO:0000781    chromosome, telomeric region    The terminal region of a linear chromosome that includes the telomeric DNA repeats and associated proteins.
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
