Unusual 2-aminopurine fluorescence from a complex of DNA and the EcoKI methyltransferase
The methyltransferase, M.EcoKI, recognizes the DNA sequence 5′-AACNNNNNNGTGC-3′ and methylates adenine at the underlined positions. DNA methylation has been shown by crystallography to occur via a base flipping mechanism and is believed to be a general mechanism for all methyltransferases. If no str...
