Alignment of the predicted polypeptides of
P. nil PNZIP, A. thaliana ATZIP,
Synechocystis spp. ORF, and P. purpurea
ORF. Amino acids that are identical in at least three of the four
different proteins are in closed boxes. The Leu zipper, hydrophilic
domain, and hydrophobic domain are marked in black. The Leu residues in
the Leu-rich region are in bold type, and the Arg and Lys residues in
the possible nuclear localization domain are in bold and underlined.
The GenBank accession numbers of PNZIP,
ATZIP, Synechocystis spp. ORF, and
P. purpurea ORF are U37437, U38232, D90899, and U38804,
respectively.
