Activation of extra copies of genes coding for nitrogenase in Rhodopseudomonas capsulata.

Nature - 1 Jan 2000

Scolnik P A, Haselkorn R

Abstract excerpt

Biological nitrogen fixation requires the nitrogenase enzyme complex, ATP, and a strong reductant. Klebsiella pneumoniae contains 15 linked nitrogen fixation (nif) genes, three of which, nifH, nifD and nifK have been sufficiently conserved in evolution that cloned K. pneumoniae nifHDK DNA will hybridize to DNA sequences from every nitrogen-fixing bacterium examined to date, including the purple, non-sulphur...
