Notes:
Abstract Rhizobium meliloti can synthesize an ammonium carrier as demonstrated by concentrative methylammonium uptake (Km= 2 μM), which is competitively inhibited by ammonium (Ki= 1.2 μM). The carrier is under nitrogen control: its synthesis is repressed by ammonium, glutamine and asparagine. The asparagine effect may be of importance for the transfer of ammonia from the bacterium to the plant in the nodule.
