Any process that stops, prevents or reduces the frequency, rate or extent of quinolinate biosynthetic process.

The chemical reactions and pathways resulting in the breakdown of tryptophan, the chiral amino acid 2-amino-3-(1H-indol-3-yl)propanoic acid.

The chemical reactions and pathways involving tryptophan, the chiral amino acid 2-amino-3-(1H-indol-3-yl)propanoic acid.

The chemical reactions and pathways involving nicotinamide, pyridine-3-carboxamide, the amide of nicotinic acid. It is a member of the B complex of vitamins and occurs widely in living organisms.

The chemical reactions and pathways resulting in the formation of aromatic amino acid family, amino acids with aromatic ring (phenylalanine, tyrosine, tryptophan).

The chemical reactions and pathways resulting in many of the chemical changes of compounds that are not necessarily required for growth and maintenance of cells, and are often unique to a taxon. In multicellular organisms secondary metabolism is generally carried out in specific cell types, and may be useful for the organism as a whole. In unicellular organisms, secondary metabolism is often used for the production of antibiotics or for the utilization and acquisition of unusual nutrients.

The chemical reactions and pathways involving quinolinate, the anion of quinolinic acid, also known as 2,3-pyridinedicarboxylic acid.

The chemical reactions and pathways involving quinolinate, the anion of quinolinic acid, also known as 2,3-pyridinedicarboxylic acid.

The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of component monomers; protein oligomers may be composed of different or identical monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.

The chemical reactions and pathways resulting in the formation of F-9775A.

The chemical reactions and pathways resulting in the formation of F-9775B.

Any process that stops, prevents or reduces the frequency, rate or extent of quinolinate biosynthetic process.

Any process that stops, prevents or reduces the frequency, rate or extent of quinolinate biosynthetic process.

The chemical reactions and pathways resulting in the formation of picolinic acid.

Any process that modulates the frequency, rate or extent of 'de novo' NAD biosynthetic process from tryptophan.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
