Figure 2: Amino acid sequence of pig Na+/K+-ATPase α1 and ß1 subunit. Amino acid residues in red are identified in the CID-MS/MS study and the underlined residues are located in the transmenbrane region. Four consensus sites (Asn-X-Ser/Thr) in the α1 subunit are marked with blue rectangles. Three N-glycosylation sites in ß1 subunit are marked with yellow rectangles.
