Figure 2.—

Sequence comparison of the translated sequences of Sorghum bicolor CAD family members, maize ZmCAD2 (Zea mays sequence AJ005702.1), and Arabidopsis AtCAD5 (Arabidopsis thaliana sequence At4g34230). The conserved amino acids identified by Youn et al. (2006) as part of the substrate binding pocket are indicated by asterisks above the sequences. The conserved glycine-rich motif G(X)GGV(L)G is indicated by a dotted line below the sequences. Italicized letters indicate completely conserved residues across all 14 sequences.
