title: [Effect of S-adenosyl-L-methionine and its analogs on site-specific binding DNA-(adenine-N6)-methyltransferase from T4 phage to the oligonucleotide substrate].
abstract: Using fluorescence of 2-aminopurine-substituted oligonucleotide duplexes, "flipping" of the target base in the process of interaction of T4 DNA-(adenine-N6)-methyltransferase (EC 2.1.1.72) with the substrate double-stranded DNA was revealed. It was shown that S-adenosyl-L-methionine, the methyl group donor, induces the reorientation of the enzyme relative to the asymmetrically modified recognition site.
