Water 139-144 delta tonoplast integral protein Arabidopsis thaliana 118-126 28279171-5 2017 In an effort to resolve these issues, we set out to introduce water permeability in Nicotiana benthamiana XIP1;1alpha (NbXIP1;1alpha), by exchanging amino acid residues of predicted alternative aromatic/arginine (ar/R) selectivity filters of NbXIP1;1alpha for residues constituting the water permeable ar/R selectivity filter of AtTIP2;1. Water 62-67 delta tonoplast integral protein Arabidopsis thaliana 329-337 27028365-5 2016 By mutational studies, we show that the identified determinants in the extended selectivity filter region are sufficient to convert a strictly water-specific human aquaporin into an AtTIP2;1-like ammonia channel.
