Abstract excerpt
The roles of the nitrogen fixation regulatory proteins NifA, FixK1, and FixK2 in the symbiotic regulation of hydrogenase structural gene expression in Bradyrhizobium japonicum have been investigated. Bacteroids from FixJ and FixK2 mutants have little or no hydrogenase activity, and extracts from...
