Identification of a promoter dependent on NifA and sigma 54 upstream of nifH in Azospirillum lipoferum.

Molecular & general genetics : MGG - 1 May 1991

Tripathi A K, Kreutzer R, Klingmüller W

Abstract excerpt

Southern hybridization experiments strongly indicate that the regulatory region of the Azospirillum lipoferum nifH gene is located on a cloned 1.1 kb BamHI-XhoI restriction fragment. By cloning this fragment into a promoter-probe plasmid in Escherichia coli, a promoter was identified oriented towards the nifH gene. Using a set of several bacterial strains and plasmids, both NifA and the alternative sigma factor,...
