Crystal structure of the Na+/H+ antiporter NhaA

Template:ABSTRACT PUBMED 15988517

Function

[NHAA_ECOLI] Na(+)/H(+) antiporter that extrudes sodium in exchange for external protons. Catalyzes the exchange of 2 H(+) per Na(+). Can mediate sodium uptake when a transmembrane pH gradient is applied. Active at alkaline pH. Activity is strongly down-regulated below pH 6.5.[1]

About this Structure

1zcd is a 2 chain structure with sequence from Escherichia coli. The December 2011 RCSB PDB Molecule of the Month feature on Complex I by David Goodsell is 10.2210/rcsb_pdb/mom_2011_12. Full crystallographic information is available from OCA.
