Abstract excerpt
Mutants of the nadI and pnuA genes were independently isolated on the basis of defects in repression of NAD biosynthetic genes and defects in transport nicotinamide mononucleotide (NMN). The mutations map at min 99 on the Salmonella chromosome, and the affected regions appear to be cotranscribed. Some pairs of nadI and pnuA mutations complement, suggesting the existence of independent functions. However,...
