(A) Schematic depictions of the domain structures of WC-1, VVD, phot1, and the ZTL family member proteins. (B) Amino acid sequence alignment of LOV domains from phototropins, WC-1, VVD, ZTL, and FKF1. This alignment was modified from ref. 13 and uses the same nomenclature for structural elements. Both LOV domains of the Adiantum capillus-veneris PHY3 and Arabidopsis thaliana phot1 were used in the alignment. Black residues are identical in all LOV domains, and gray residues are identical in most LOV domains. Asterisks mark the 11 FMN-interacting residues found in the LOV2 domain of Adiantum PHY3. Arrows mark the four residues that are essential for the light function of WC-1. For simplicity, the first residue of each LOV domain was numbered as the first residue.
