title: Primary structure diversity of prokaryotic diheme cytochromes c.
abstract: The primary structure of five diheme cytochromes from photosynthetic bacteria recently determined in our laboratory lead to the first insights in the structural diversity of this type of cytochrome. A schematic overview is given, relating these structures to the four diheme cytochrome sequences already available. The comparison reveals unexpected homologies.
