人胸腺嘧啶DNA糖基化酶(hTDG)能有效地切割5-羧基胞嘧啶(5caC),5caC是最近发现的胞嘧啶去甲基化途径中5-甲基胞嘧啶的关键氧化产物。我们在这里提出的晶体结构的hTDG催化结构域的复合物与双链DNA含有5caC或氟化类似物。这些结构,连同生物化学和计算分析,揭示了5caC被特异性地识别在hTDG的活性位点中,支持TDG在哺乳动物5-甲基胞嘧啶(5 mC)去甲基化中的作用。
Human thymine DNA glycosylase (hTDG) efficiently excises 5-carboxylcytosine (5caC), a key oxidation product of 5-methylcytosine in a recently discovered cytosine demethylation pathway. We present here the crystal structures of hTDG catalytic domain in complex with duplex DNA containing either 5caC or a fluorinated analog. These structures, together with biochemical and computational analyses, reveal that 5caC is specifically recognized in the active site of hTDG, supporting the role of TDG in mammalian 5-methylcytosine (5mC) demethylation.
