WebJan 1, 2016 · ATP Binding Cassette G (ABCG) transporters, comprising the half-size white/brown complex (WBC) transporters and the full-size pleiotropic drug resistance (PDR) subgroup members, are markedly expanded in plants, with more than 40 members in both Arabidopsis and rice. 6 Although plant WBCs and PDRs are phylogenetically … WebSep 26, 2024 · Models of ABCG transporters: Comparative homology modeling is based on the assumption that proteins sharing sequence homology also share folds and thus structures. A known structure with a sequence identity higher than 20% can serve as a proper template structure [ [ 92] ].
