Assembly and functional analysis of the K. oxytoca Fe–S cluster assembly system (nifUS) in E. coli 78-7. a Linear view of the Fe–S cluster assembly gene region in pBluescriptII SK (+)-derived plasmid. b Relative nitrogenase activity of wild-type Paenibacillus sp. WLY78, E. coli 78-7 [pBluescriptIISK (+)] and E. coli 78-7 (nifUS). E. coli 78-7 [pBluescriptII SK (+)] was used as a control. Each experiment was repeated at least three times, and the error bars represent standard error
