Figure 4From: Conservation, diversification and expansion of C2H2 zinc finger proteins in the Arabidopsis thaliana genome Amino acid residues in helix positions -1, 3 and 6 in ZF domains of groups A1a to A1d. Conserved amino acid residues with high specificity to particular DNA bases according to a proposed ZF-DNA "recognition code" and corresponding putative DNA bases are highlighted in yellow.Back to article page
