~~'''~~Crystal Structure of Na,K-ATPase N-domain~~'''~~

===Crystal Structure of Na,K-ATPase N-domain===

~~==Overview==~~

<!--

The ~~structure of~~ the ~~N-domain of porcine alpha~~(~~2) Na,K-ATPase was determined crystallographically to 3~~.~~2A resolution by isomorphous heavy-atom replacement using a single mercury derivative~~. The structure was finally refined against 2.6A resolution synchrotron data. The domain forms a seven-stranded antiparallel beta-sheet with two additional beta-strands forming a hairpin and five alpha-helices. Approximately 75% of the residues were superimposable with residues from the structure of Ca-ATPase N-domain, ~~and a structure-based sequence alignment~~ is ~~presented. The positions of key residues are discussed in relation to the pattern of hydrophobicity, charge and sequence conservation of~~ the ~~molecular surface. The structure of a hexahistidine tag binding to nickel ions is presented~~.
