Fig. 2

Multiple sequence alignment of select members of FT/CETS/PEBP/RKIP/YbhB family. Sequence identifiers in GenBank or PDB are shown before each sequence. For the arabidopsis proteins, gene product names and AGI locus codes are also shown. In the Secondary structure lines above the alignment, s stands for a beta-strand and h stands for an alpha-helix. Conserved hydrophobic residues (I, L, M, V, F, Y, W) are indicated by yellow shading, conserved small-side-chain or turn/kink-prone residues (A, G, S, P) are indicated by bold red type, and the conserved constellation of charged residues discussed in the text are marked as follows: gray-shaded blue type, two conserved aspartates; cyan shading, two conserved histidines; and black-shaded white type, conserved arginine. In the sequence XP_024370999.1, the bold underlined X marks the position of a low-complexity sequence insertion that most likely represents a falsely predicted exon
