| Abstract | A number of evolutionarily-related proteins have been found to be involved in the transport of ammonium ions across membranes [ 8062823, 8621394].
Members of this family include:
- Saccharomyces cerevisiae ammonium transporters MEP1, MEP2 and MEP3.
- Arabidopsis thaliana high affinity ammonium transporter (gene AMT1).
- Corynebacterium glutamicum ammonium and methylammonium transport system.
- Escherichia coli putative ammonium transporter amtB.
- Bacillus subtilis nrgA.
- Mycobacterium tuberculosis hypothetical protein MtCY338.09c.
- Synechocystis sp. (strain PCC 6803) hypothetical proteins sll0108, sll0537 and sll1017.
- Methanococcus jannaschii hypothetical proteins MJ0058 and MJ1343.
- Caenorhabditis elegans hypothetical proteins C05E11.4, F49E11.3 and M195.3.
As expected by their transport function, these proteins are highly hydrophobic
and seem to contain from 10 to 12 transmembrane domains. |

Alignments of sequences to 1 models
in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Browse and view proteins in genomes which have
different domain combinations including a Ammonium transporter domain.
|
Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.
|
|
Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.
|
There are 1 hidden Markov models representing the Ammonium transporter superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
