Bartonellae are hemotropic bacteria, agents responsible for emerging zoonoses. These Alphaproteobacteria are heme auxotroph which must import heme for supporting their growth, as they cannot synthesize it. Therefore, Bartonella genome encodes for a complete heme uptake system allowing the transportation of this compound in the cytoplasm. Heme has also been shown to be used as an iron source for Bartonella. Similarly to other bacteria which use heme as an iron source, Bartonellae must degrade it to allow the release of iron. For Bartonella, the genes cluster devoted to the heme uptake system contains a gene encoding for a polypeptide that shares homologies with heme trafficking or degrading enzymes. Using complementation of an E. coli mutant...
