26-310 2.90e-28

CorA-like Mg2+ transporter protein; The CorA transport system is the primary Mg2+ influx system of Salmonella typhimurium and Escherichia coli. CorA is virtually ubiquitous in the Bacteria and Archaea. There are also eukaryotic relatives of this protein. The family includes the MRS2 protein from yeast that is thought to be an RNA splicing protein. However its membership of this family suggests that its effect on splicing is due to altered magnesium levels in the cell.

uncharacterized bacterial subfamily of the Escherichia coli CorA-Salmonella typhimurium ZntB family; A uncharacterized subfamily of the Escherichia coli CorA-Salmonella typhimurium ZntB (EcCorA-ZntB_like) family of the MIT superfamily of essential membrane proteins involved in transporting divalent cations (uptake or efflux) across membranes.The EcCorA-ZntB-like family includes the Mg2+ transporters Escherichia coli and Salmonella typhimurium CorAs, which can also transport Co2+, and Ni2+. Structures of the intracellular domain of EcCorA-ZntB-like family members, Vibrio parahaemolyticus and Salmonella typhimurium ZntB, form funnel-shaped homopentamers, the tip of the funnel is formed from two C-terminal transmembrane (TM) helices from each monomer, and the large opening of the funnel from the N-terminal cytoplasmic domains. The GMN signature motif of the MIT superfamily occurs just after TM1, mutation within this motif is known to abolish Mg2+ transport through Salmonella typhimurium CorA. Natural variants such as GVN and GIN, such as occur in some ZntB family proteins, may be associated with the transport of different divalent cations, such as zinc and cadmium. The functional diversity of MIT transporters may also be due to minor structural differences regulating gating, substrate selection, and transport.

CorA-like Mg2+ transporter protein; The CorA transport system is the primary Mg2+ influx system of Salmonella typhimurium and Escherichia coli. CorA is virtually ubiquitous in the Bacteria and Archaea. There are also eukaryotic relatives of this protein. The family includes the MRS2 protein from yeast that is thought to be an RNA splicing protein. However its membership of this family suggests that its effect on splicing is due to altered magnesium levels in the cell.

Thermotoga maritima CorA-like family; This family belongs to the MIT superfamily of essential membrane proteins involved in transporting divalent cations (uptake or efflux) across membranes. Members of the Thermotoga maritima CorA_like family are found in all three kingdoms of life. It is a functionally diverse family, in addition to the CorA Co2+ transporter from the hyperthermophilic Thermotoga maritima, it includes three Saccharomyces cerevisiae members: two plasma membrane proteins, the Mg2+ transporter Alr1p/Swc3p and the putative Mg2+ transporter, Alr2p, and the vacuole membrane protein Mnr2p, a putative Mg2+ transporter. Thermotoga maritima CorA forms funnel-shaped homopentamers, the tip of the funnel is formed from two C-terminal transmembrane (TM) helices from each monomer, and the large opening of the funnel from the N-terminal cytoplasmic domains. The GMN signature motif of the MIT superfamily occurs just after TM1, mutation within this motif is known to abolish Mg2+ transport by Alr1p. Natural variants in this signature sequence may be associated with the transport of different divalent cations. The functional diversity of the MIT superfamily may also be due to minor structural differences regulating gating, substrate selection, and transport.

Escherichia coli CorA-Salmonella typhimurium ZntB_like family; A family of the MIT superfamily of essential membrane proteins involved in transporting divalent cations (uptake or efflux) across membranes. Members of this family are found in all three kingdoms of life. It is a functionally diverse family, including the Mg2+ transporters Escherichia coli and Salmonella typhimurium CorAs (which can also transport Co2+, and Ni2+ ), and the Zn2+ transporter Salmonella typhimurium ZntB which mediates the efflux of Zn2+ (and Cd2+). It also includes two Saccharomyces cerevisiae members: the inner membrane Mg2+ transporters Mfm1p/Lpe10p, and Mrs2p, and a family of Arabidopsis thaliana members (AtMGTs) some of which are localized to distinct tissues, and not all of which can transport Mg2+. Structures of the intracellular domain of Vibrio parahaemolyticus and Salmonella typhimurium ZntB form funnel-shaped homopentamers, the tip of the funnel is formed from two C-terminal transmembrane (TM) helices from each monomer, and the large opening of the funnel from the N-terminal cytoplasmic domains. The GMN signature motif of the MIT superfamily occurs just after TM1, mutation within this motif is known to abolish Mg2+ transport through Salmonella typhimurium CorA, and Mrs2p. Natural variants such as GVN and GIN, such as occur in some ZntB family proteins, may be associated with the transport of different divalent cations, such as zinc and cadmium. The functional diversity of MIT transporters may also be due to minor structural differences regulating gating, substrate selection, and transport.

Natural variants such as GVN and GIN, as in some ZntB family proteins, may be associated with the transport of different divalent cations, such as zinc and cadmium. The functional diversity of MIT transporters may also be due to minor structural differences regulating gating, substrate selection, and transport.

Uncharacterized subfamily of the Thermotoga maritima CorA-like family; This subfamily belongs to the Thermotoga maritima CorA (TmCorA)-like family of the MIT superfamily of essential membrane proteins involved in transporting divalent cations (uptake or efflux) across membranes. Members of the TmCorA-like family are found in all three kingdoms of life. It is a functionally diverse family which includes the CorA Co2+ transporter from the hyperthermophilic Thermotoga maritima, and three Saccharomyces cerevisiae proteins: two located in the plasma membrane: the Mg2+ transporter Alr1p/Swc3p and the putative Mg2+ transporter, Alr2p, and the vacuole membrane protein Mnr2p, a putative Mg2+ transporter. Thermotoga maritima CorA forms funnel-shaped homopentamers, the tip of the funnel is formed from two C-terminal transmembrane (TM) helices from each monomer, and the large opening of the funnel from the N-terminal cytoplasmic domains. The GMN signature motif of the MIT superfamily occurs just after TM1, mutation within this motif is known to abolish Mg2+ transport by a related protein, Saccharomyces cerevisiae Alr1p. Natural variants in this signature sequence may be associated with the transport of different divalent cations. The functional diversity of the MIT superfamily may also be due to minor structural differences regulating gating, substrate selection, and transport.

Thermotoga maritima CorA_like subfamily; This subfamily belongs to the Thermotoga maritima CorA (TmCorA)-family of the MIT superfamily of essential membrane proteins involved in transporting divalent cations (uptake or efflux) across membranes. Members of this subfamily are found in all three kingdoms of life. It is functionally diverse subfamily, in addition to the CorA Co2+ transporter from the hyperthermophilic Thermotoga maritima, it includes Methanosarcina mazei CorA which may be involved in transport of copper and/or other divalent metal ions. Thermotoga maritima CorA forms funnel-shaped homopentamers, the tip of the funnel is formed from two C-terminal transmembrane (TM) helices from each monomer, and the large opening of the funnel from the N-terminal cytoplasmic domains. The GMN signature motif of the MIT superfamily occurs just after TM1, mutation within this motif is known to abolish Mg2+ transport by a related protein, Saccharomyces cerevisiae Alr1p. Natural variants in this signature sequence may be associated with the transport of different divalent cations. The functional diversity of the MIT superfamily may also be due to minor structural differences regulating gating, substrate selection, and transport.
