Ammonia acquisition in enteric bacteria: physiological role of the ammonium/methylammonium transport B (AmtB) protein.

Proceedings of the National Academy of Sciences of the United States of America - 9 Jun 1998

Soupene E, He L, Yan D, Kustu S

Abstract excerpt

Homologues of the amtB gene of enteric bacteria exist in all three domains of life. Although their products are required for transport of the ammonium analogue methylammonium in washed cells, only in Saccharomyces cerevisiae have they been shown to be necessary for growth at low NH4+ concentrations. We now demonstrate that an amtB strain of Escherichia coli also grows slowly at low NH4+ concentrations in batch...
