Polar mutations, mostly Mu and Tn insertions, were used to study the transcriptional organization of the nif gene cluster of Klebsiella pneumoniae, but there remained some ambiguity in the operon structure of the nifF,-M,-V,-S,-U genes. Complementation data presented here confirm that nifUSVM is a single operon transcribed from nifU to nifM. However, the… (More)
