The activity and extent of adenylylation of glutamine synthetase was examined in both free-living and bacteroid forms of Rhizobium japonicum in the presence of excess ammonia. Ammonia caused an apparent repression of glutamine synthetase in free-living R. japonicum and adenylylation of the enzyme was also increased. In contrast, neither the activity nor the extent of adenylylation of the bacteroid enzyme was consistently affected by ammonium treatment of bacteroid suspensions. Similar results… Expand
