Activation of Klebsiella pneumoniae and Rhizobium meliloti nitrogenase promoters by gin (ntr) regulatory proteins (nitrogen metabolism regulation/symbiotic nitrogen fixation/lac fusions)

  • VENKATESAN SUNDARESANt

Abstract

We have studied the expression, in different Escherichia coli gin (ntr) mutants, of fusions (constructed in vitro) of the nifHDK (nitrogenase) promoters from Klebsiela pneumoniae and Rhizobium meliloti to E. coli lacZ. Derepression of the K. pneumoniae nifH::lacZ fusion requires the glnF (ntrA) gene product in addition to the K. pneumoniae nifA gene product… (More)
