Abstract excerpt
In Bradyrhizobium japonicum, the nitrogen-fixing symbiont of soybeans, we have identified a haem uptake system, Hmu, that comprises a cluster of nine open reading frames. Predicted products of these genes include: HmuR, a TonB-dependent haem receptor in the outer membrane; HmuT, a periplasmic haem-binding protein; and HmuUV, an ABC transporter in the inner membrane. Furthermore, we identified homologues of ExbBD...
