Caption: Overlay of the known structures of CHI-fold proteins from Arabidopsis thaliana and alfalfa (Medicago sativa). Protein backbones are shown as ribbons, with β-strands depicted as flat arrows (blue), α-helices as broad coils (orange), and loops as thin rope (gray). The various bound ligands in these proteins (naringenin in alfalfa CHI, and fatty acids in AtFAP1 and AtFAP3) are shown as van der Waals spheres.
