Figure 2: Structures of the closed and open conformations of
SoPIP2;1. a, Stereo models of SoPIP2;1 in its open (blue) and
closed (green) conformations overlaid on that of AQP0 (light
grey; Protein Data Bank (PDB) entry 1YMG) and AQP1 (grey; PDB
entry 1J4N). b, c, Electron density for loop D in the closed (b)
and open (c) conformations. The structural model of the closed
conformation is coloured green and the open conformation is
coloured blue. Both 2F[o] - F[c] electron density maps are
contoured at 1.0 .
Residual electron density in c indicates that the closed
conformation is also present in partial occupancy.
