(A) Gene organization in the fumarate reductase operon (frdCAB) of C. jejuni. (B) Gene organization in the succinate dehydrogenase operon (sdhABC) of C. jejuni. (C) Directly downstream of the frdCAB operons is Cj0411, which encodes a putative GTPase. The insertion sites of the chloramphenicol cassette (striped arrows) used for mutagenesis are indicated. The directions of the arrows indicate the transcriptional orientations of the genes. Unrelated genes directly downstream of the genes of interest are indicated by black arrows.
