Assembly and functional analysis of the Paenibacillus Fe–S cluster assembly systems (suf and isc) in E. coli. 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 [pBluescriptII SK (+)], E. coli 78-7 (suf) and E. coli 78-7 (isc). 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
