Fig. 7From: Single amino acid substitutions in the selectivity filter render NbXIP1;1α aquaporin water permeableEstimation of the radius of the pore in NbXIP1;1αwt and NbXIP1;1α mutants. WT (NbXIP1;1αwt), Mutant 1 (NbXIP1;1αL79G/I102H/V242I), Mutant 2 (NbXIP1;1αL79G/I102H/T246I), Mutant 3 (NbXIP1;1αL79G), Mutant 4 (NbXIP1;1αI102H), Mutant 5 (NbXIP1;1αV242I), Mutant 6 (NbXIP1;1αL79G/I102H), Mutant 7 (NbXIP1;1αI102H/V242I) and Mutant 8 (NbXIP1;1αL79G/V242I). The program HOLE [38] was used to estimate the radius of the pore in the models. See also Additional file 7: Figure S2 in the supplementary informationBack to article page
