Periodic table of the metalloids. Metalloid substrates of aquaglyceroporins are shown both in their position in the periodic table and as molecular models. The size of each metalloid is shown in scale relative to glycerol (right). Atomic coordinates from the Cambridge Structural Database  were modeled with InsightII to calculate partial charges (blue, positive; red, negative; green and yellow reflect intermediate charges between blue and red) and plotted with PyMol. Beside each metalloid is listed its transport proteins. Each is a NIP except for Lsi2, which is an ArsB homolog. Species abbreviations: At, Arabidopsis thaliana; Lj, Lotus japonicus; Os, Oryza sativa; Zm, Zea mays.
