title: Regulation of nitrogen metabolism genes by nifA gene product in Klebsiella pneumoniae.
abstract: The Klebsiella pneumoniae nifA gene product, which is known to activate expression of the nitrogen fixation (nif) structural genes, is shown here also to be able to substitute for the product of the gene glnG (ntrC) in the regulation of other nitrogen metabolism genes. An evolutionary relationship between the nifA and glnG genes is suggested.
