Bacteriophage mu-induced deletions in a plasmid containing the nif (N2 fixation) genes of Klebsiella pneumoniae.

RESUMO
Five plasmids with insertions of a heat-inducible Mu prophage in a Mu-sensitive and P1-sensitive derivative of plasmid pRD1, a recombinant R factor containing the his-nif region of Klebsiella pneumoniae, were isolated and characterized. In one plasmid containing the Mu prophage integrated at the his-distal end of nif, selection for heat resistance resulted in the generation of deletions extending from the Mu prophage into the nif region. Thirty of these deltions were used to map 26 point mutations in nif.
