Alignment of the AP2 domain of 54 putative DREB proteins from common bean. Position 14th and 19th, described as important for protein binding, are separated by spaces along the sequences. Position 14th presents 100% conservation of the amino acid valine (V), while the 19th varies, although glutamic acid (E) and leucine (L) are the most frequent. Other sequences than the 54 DREB were compared in the alignment. Those sequences fitted as putative DREB in the phylogenetic analysis, but not for amino acid conservation.
