Abstract excerpt
The cycHJKL operon of Rhizobium leguminosarum has previously been shown to be involved in the maturation of cytochrome c, possibly by its involvement in the covalent attachment of haem to the apoprotein. Mutations in the cycHJKL genes abolish symbiotic nitrogen fixation. Here, we show that cyc mu...
