摘要: The RNA polymerase sigma factor σN is unique amongst bacterial factors both in terms of its structure and the mechanism transcription initiation mediated by EσN holoenzyme (Kustu et al., 1989; Merrick,1993). widely distributed eubacteria required for a wide variety genes, including example flagellar genes Caulobacter, xylene degradation Pseudomonas, hydrogenase A Icedigenes nitrogen fixation many, though not all, diazotrophs. structural gene, rpoN, has now been cloned characterised from at least 15 genera majority cases where sequence analysis extended beyond rpoN conserved set linked identified (Merrick Coppard, Merrick, 1993).
