Figure 3.

Sequence comparisons of the aquaporins PiconPIP2s, PiconPIP1;2, SoPIP2;1, ZmPIP2;1, and McPIP2;1. The alignment of loops B and D [49]. The first few letters of each AQP name refer to the plant species (Picon, Pinus contorta; So, Spinacia oleracea; Zm, Zea mays; Mc, Mesembryanthemum crystallinum). Amino acid residues are colored according to their side chain: large aliphatic (green), small aliphatic (gray), basic (blue), acidic (red), hydroxyl non-aromatic (purple), and aromatic (royal blue). Amino acid residues involved in anchoring of loop D to loop B and the N-terminus are shown. Sequence alignment was done using MUSCLE.
