physiological function | a total of 74 genes are induced in cells grown with nitrate as N-source compared with ammonium, including nasTSABGHC and ntrBC genes. The nasABGHC genes constitute a transcriptional unit. The nasTS and nasABGHC transcripts are detected at similar levels with nitrate or glutamate as N-source, but nasABGHC transcript is undetectable in ammonium-grown cells. The nasT mutant lacks both nasABGHC transcript and nicotinamide adenine dinucleotide (NADH)-dependent nitrate reductase activity. The nasS mutant shows similar levels of the nasABGHC transcript to the wild-type strain and displays NasG protein and NADH-nitrate reductase activity with all N-sources tested, except with ammonium | Paracoccus denitrificans |
