Alignment of tobacco NtMEK2 with Arabidopsis AtMEK4 (BAA28830) and human MEK1 (Q02750). Roman numerals indicate the 11 conserved subdomains of the kinase catalytic domain. Numbers in parentheses indicate the percentage of amino acid sequence identity to the NtMEK2. The conserved Ser/Thr residues (Thr-227, Ser-233, and Thr-237) between subdomains VII and VIII for MAPKKs are marked with asterisks underneath. The conserved Lys-111 that is important for the ATP binding is marked with a dot.
