Abstract excerpt
Sinorhizobium meliloti, the endosymbiont of Medicago sativa, can use haem compounds, including haemoglobin and leghaemoglobin, when growing in the free-living state. The components of the system involved in haem acquisition were confirmed to be ShmR, an outer membrane receptor, and HmuTUV, predicted to be an ABC transport system comprising a periplasmic protein, a permease and an ATPase respectively. The roles of...
