title: Nitrate reductase and cytochrome bnitrate reductase structural genes as parts of the nitrate reductase operon.
abstract: The existence of a nitrate-reductase operon in the tryptophane region was deduced from the effects of prophage insertion in each of chlI and chlC genes and from transposition of the Mu-mediated host DNA fragments of F-prime. This operon appears to be polarized from chlC to chlI and the gene order in the region is trp -- chlI -- chlC -- purB.
