Apertures and architecture analysis of the inner surface for the members in the classical AQP subfamily in oysters. The graphs in the first line represent the individual structure for each member from the non-cytoplasm side. The amino acids in the Ar/R region were highlighted by elements. The graphs in the second line represent the corresponding partial enlarged view of the amino acids in the Ar/R region. The graphs in the third line represent the independent inner surface profiles of the channel along the z-axis. The regions colored by red represent the radius was narrower than 1 Å. The regions colored by green represent the radius was varied from 1 to 2 Å. The radius of the regions that larger than 2 Å were colored by blue. The graphs in the fourth line represent the individual channel radius curves along the z-axis
