Journal ArticleDOI
Identification of a new class of nitrogen fixation genes in Rhodobacter capsulatus: a putative membrane complex involved in electron transport to nitrogenase

TL;DR: The hypothesis that this new class of nitrogen fixation genes encodes components of an electron transfer system to nitrogenase was corroborated by analysing the effect of metronidazole.
Journal ArticleDOI
DNA sequence and genetic analysis of the Rhodobacter capsulatus nifENX gene region: homology between NifX and NifB suggests involvement of NifX in processing of the iron-molybdenum cofactor
TL;DR: Interposon-induced insertion and deletion mutants proved that nifE and nifN were necessary for nitrogen fixation in R. capsulatus and suggested that NifX and NifY might play a role in maturation and/or stability of the iron-molybdenum cofactor.
Journal ArticleDOI
Mapping and characterization of the promoter elements of the regulatory nif genes rpoN, nifA1 and nifA2 in Rhodobacter capsulatus
TL;DR: Mapping of the promoter elements involved in the expression of nif A copy 1 and copy 2 identified a novel promoter type that is likely to represent the binding site of NTRC in R. capsulatus.
Journal ArticleDOI
Functional analysis of the cysteine motifs in the ferredoxin-like protein FdxN of Rhizobium meliloti involved in symbiotic nitrogen fixation.
TL;DR: The deduced sequence of the FdxN protein is characterized by two cysteine motifs typical of bacterial-type ferredoxins, and it was predicted that these amino acid residues form a loop, which does not alter the relative positions of the neighbouring cysteines.
