- W4231317967 abstract "The Rhodobacter capsulatus nrfA gene product exhibits extensive similarity to the nif (nitrogen fixation) regulatory factor NrfA of Azorhizobium caulinodans and the nucleoid-associated protein Hfq of Escherichia coli. Mutational analysis revealed that, in contrast to the situation in A. caulinodans, NrfA is not essential for diazotrophic growth of R. capsulatus, but it is required for maximal growth rates with N2 as sole nitrogen source via either molybdenum nitrogenase or the alternative nitrogenase. NrfA was shown to control N2 fixation in R. capsulatus at the level of expression of the regulatory genes nifA1, nifA2 and anfA, encoding the transcriptional activators of all the other nitrogen fixation genes." @default.
