As an intermediate, α-amino-β-carboxy-muconate-semialdehyde can be cyclized to quinolinic acid, while α-amino-β-carboxy-muconate-semialdehyde decarboxylase converts α-amino-β-carboxy-muconate-semialdehyde to picolinic acid, which limits the flux from tryptophan to NAD + ( + biosynthesis is the conversion of quinolinic acid to nicotinate mononucleotide by quinolinate phosphoribosyltransferase ( + by NAD synthase using glutamine as a nitrogen donor ( 2.2 Salvage pathway To maintain cellular NAD + levels, most NAD + is recycled from its precursors, such as nicotinamide mononucleotide, nicotinamide, nicotinic acid, and nicotinamide riboside, in the salvage pathway (Figure 1) ( + consumption reactions via both NAD + -dependent deacylation and ADP ribosylation into nicotinamide mononucleotides by nicotinamide phosphoribosyltransferase
