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.
从在基本培养基中生长的大肠杆菌nadC营养缺陷型的培养液中分离出的一种化合物,能支持nadA和nadB突变体的生长。这种代谢物呈现出不同于喹啉酸的紫外光吸收光谱和质谱。该化合物可能是喹啉酸的前体,而喹啉酸是烟酰胺腺嘌呤二核苷酸生物合成中的一种中间体。
