Analysis of regulation of Klebsiella pneumoniae nitrogen fixation (nif) gene cluster with gene fusions.

R Dixon, R R Eady, G Espin, S Hill, M Iaccarino, D Kahn, M Merrick.   

Abstract

Gene fusions in which the lac genes are under the control of each promoter in the Klebsiella pneumoniae, nitrogen fixation (nif) gene cluster have been constructed. These fusions have been used to examine positive control of the cluster and the response of individual genes to repression by ammonia and oxygen. De-repression of nif transcriptional units is coordinate and molybdate is required for maximal expression of the structural gene operon, which is autogenously regulated.
