Structure and expression of the alternative sigma factor, RpoN, in Rhodobacter capsulatus; physiological relevance of an autoactivated nifU2-rpoN superoperon.

Molecular microbiology - 1 Jan 1994

Cullen P J, Foster-Hartnett D, Gabbert K K, Kranz R G

Abstract excerpt

The alternative sigma factor, RpoN (sigma 54) is responsible for recruiting core RNA polymerase to the promoters of genes required for diverse physiological functions in a variety of eubacterial species. The RpoN protein in Rhodobacter capsulatus is a putative sigma factor specific for nitrogen fixation (nif) genes. Insertional mutagenesis was used to define regions important for the function of the R. capsulatus...
