A DNA (cytosine)-5-methyltransferase from Haemophilus aegyptius (M.Hae III), which catalyzes methyl transfer from S-adenosyl-L-methionine to DNA, has been crystallized as a covalent complex with a suicide oligonucleotide substrate. Crystals of the co-complex were grown by vapor diffusion with hanging droplets

The human immunodeficiency virus (HIV) type 1 reverse transcriptase (RT) is an important target for therapeutic intervention and for HIV-1-specific cytotoxic T lymphocytes (CTL). An HLA-A2-restricted CTL epitope containing the sequence YMDD, which is highly conserved among human and animal
DNA (cytosine-5)-methyltransferases can cause deamination of cytosine when the cofactor S-adenosylmethionine (AdoMet) is limiting and thus function as sequence-specific C-->U mutator enzymes. Here we explored whether mutations causing inactivation of the cofactor binding activity of the HpaII methyltransferase, thus mimicking
The product of the dcm gene is the only DNA cytosine-C5 methyltransferase of Escherichia coli K-12; it catalyses transfer of a methyl group from S-adenosyl methionine (SAM) to the C-5 position of the inner cytosine residue of the cognate sequence
Jones and coworkers demonstrated a qualitative correlation between 5-azacytidine and some of its analogs in inducing changes in cell morphology and their ability in preventing DNA methylation. Previously, we evaluated the same compounds to determine their ability to induce trifluorothymidine
We offer a variety of small molecule research tools, such as transcription factor modulators, inhibitors of chromatin modifying enzymes, and agonists/antagonists for target identification and validation in gene regulation research; a selection of these research tools is shown below.
