Conserved sequence motif DPPY in region IV of the phage T4 Dam DNA-[N6-adenine]-methyltransferase is important for S-adenosyl-L-methionine binding.
Comparison of the deduced amino acid sequences of DNA-[N6-adenine]-methyltransferases has revealed several conserved regions. All of these enzymes contain a DPPY [or closely related] motif. By site-directed mutagenesis of a cloned T4 dam gene, we have altered the first proline residue in this motif...
