Abstract excerpt
Bradyrhizobium japonicum possesses three soluble c-type cytochromes, c550, c552, and c555. The genes for cytochromes c552 (cycB) and c555 (cycC) were characterized previously. Here we report the cloning, sequencing, and mutational analysis of the cytochrome c550 gene (cycA). A B. japonicum mutant with an insertion in cycA failed to synthesize a 12-kDa c-type cytochrome. This protein was detectable in the cycA...
