In mammals, DNA methylation patterns are established by two de novo DNA methyltransferases, DNMT3A and DNMT3B. Here the authors report the crystal structures of DNMT3B in complex with both CpG and CpA DNA, providing insight into the substrate-recognition mechanism underpinning the divergent genomic methylation activities of DNMT3A and DNMT3B.
