ammonium transporter functions in the uptake or transport of ammonia

Date:

2017-05-24

Members of this protein family are well conserved subclass of putative ammonimum transporters, belonging to the much broader set of ammonium/methylammonium transporter described by TIGR00836. Species with this transporter tend to be marine bacteria. Partial phylogenetic profiling (PPP) picks a member of this protein family as the single best-scoring protein vs. a reference profile for the marine environment Genome Property for a large number of different query genomes. This finding by PPP suggests that this transporter family represents an important adaptation to the marine environment.

The Ammonium Transporter (Amt) Family (TC 2.A.49) All functionally characterized members of the Amt family are ammonia or ammonium uptake transporters. Some, but not others, also transport methylammonium. The mechanism of energy coupling, if any, to methyl-NH2 or NH3 uptake by the AmtB protein of E. coli is not entirely clear. NH4+ uniport driven by the pmf, energy independent NH3 facilitation, and NH4+/K+ antiport have been proposed as possible transport mechanisms. In Corynebacterium glutamicum and Arabidopsis thaliana, uptake via the Amt1 homologues of AmtB has been reported to be driven by the pmf.
