Identification of completely conserved amino acid residues in sequence motifs 1-3 of DGAT1s. (A) DGAT1-Motif 1 (GL Block; The boxed E residue is mutated in TmDGAT1), (B) DGAT1-Motif 2 (KSR Block), (C) DGAT1-Motif 3 (PTR Block; The boxed P residues are also conserved in DGAT2s). Multiple sequence alignment was performed using 55 full-length DGAT1 protein sequences from 45 organisms (listed in Table 1). The completely conserved amino acid residues are highlighted in red on yellow. Other color code and related information are described briefly in Figure 2 legend and with details in "Methods" section.
