Notes
AmtB is a trimeric inner membrane protein. Each subunit has 11 TM helices; a predicted N-terminal 12th TM helix is actually a cleaved signal peptide. Ammonium is proposed to bind to the periplasmic face of AmtB and then to be deprotonated to ammonia for diffusion through the AmtB channel, then reprotonated by water to hydrate the ammonia gas to ammonium ion in the cytoplasm. AmtB enables growth on ammonium as sole nitrogen source at low ammonium ion concentrations (Soupene, 1998). The human Rh proteins are AmtB homologs and have been variously proposed to act as ammonia channels or as carbon dioxide gas channels.[4]
