2 * 48000, AtNRT2.1, SDS-PAGE, + 2 * 26000, myc-tagged AtNAR2.1, SDS-PAGE, the functional unit for high-affinity nitrate influx may be a tetramer consisting of two subunits each of AtNRT2.1 and AtNAR2.1
ATP-binding cassette-type ATPase, NrtC and NrtD constitute the membrane transporter complex, NrtB is a hydrophobic protein with five putative membrane-spanning segments, the substrate-binding protein NrtA is tightly bound to the cytoplasmic membrane, an NrtA-like extra domain is linked to one of the ATP-binding subunits
the nrtB, nrtC and nrtD genes encode membrane components of the ATP-binding cassette transporter, the 45000 Da nrtA gene product is a nitrate- and nitrite-binding lipoprotein
