From: Structure determination and activity manipulation of the turfgrass ABA receptor FePYR1
Comparison of FePYR1 with the members of subfamily-I and -III in Arabidopsis. (A) Sequence alignment of FePYR1 with subfamily-I and subfamily-III members in Arabidopsis thaliana. Variant amino acids in the important regions are highlighted with different colors. (B) Interaction of mutants of FePYR1 with indicated amino acid substitutions with AtHAB1 in the presence of 5 μM ABA assessed by Alpha-Screen assay. (C) A comparison view of the non-polar triplet residues from AtPYL9 and FePYR1 in contact with ABA. The ABA molecules (green) and triplet residues are shown as stick models with their van der Waals surfaces (dots).
