RT ammonia uptake.";
RL EMBO J. 26:589-599(2007).
CC -!- FUNCTION: Involved in the uptake of ammonium/ammonia (NH(4)(+)/NH(3))
CC (By similarity). Transport is electrogenic (By similarity).
CC {ECO:0000250|UniProtKB:O29285}.
CC -!- ACTIVITY REGULATION: Activity is regulated by the nitrogen regulatory
CC protein GlnK1 via direct interaction (PubMed:17203075). Formation of
CC the GlnK1/Amt1 complex is decreased in the presence of Mg-ATP or 2-
CC oxoglutarate. The presence of both effectors abolishes the formation of
CC the complex (PubMed:17203075). {ECO:0000269|PubMed:17203075}.
CC -!- SUBUNIT: Homotrimer (PubMed:17203075). Interacts and forms a complex
CC with GlnK1 (PubMed:17203075). {ECO:0000269|PubMed:17203075}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the ammonia transporter channel (TC 1.A.11.2)
CC family. {ECO:0000305}.
