Figure 9From: Conservation, diversification and expansion of C2H2 zinc finger proteins in the Arabidopsis thaliana genome Comparison of putative DNA contacting amino acids in SUP and ZPT2-2. The ZF helix sequences, their conserved C-terminal flanks, suggested DNA contacting amino acid residues (+) and positions mutated in DNA-binding studies and abolishing binding activity (§). Signature positions are highlighted in yellow.Back to article page
