Abstract:
:A compound, isolated from the culture fluid of a nadC auxotroph of Escherichia coli grown in a minimal medium, supports the growth of both a nadA and a nadB mutant. This metabolite exhibits an ultraviolet light absorption spectrum and a mass spectrum, different from quinolinic acid. This compound may be the precursor of quinolinic acid, an intermediate in the biosynthesis of nicotinamide adenosine dinucleotide.
