Aquaporin Z is the first identified prokaryotic water channel in Escherichia coli with a high water permeability and strict substrate selectivity. Here we report nearly complete (94% of amino acid residues) 13C and 15N chemical shift assignments of AqpZ reconstituted in the lipid bilayers using a set of 2D and 3D magic angle spinning solid-state NMR spectra. Secondary structure of AqpZ predicted from chemical shift assignments is generally similar to that of X-ray structure with a number of differences in loop and near-loop regions. The BMRB accession number of the assignments is 27244.
