1 Excision of thymine and 5-hydroxymethyluracil by the MBD4 DNA glycosylase domain: structural basis and implications for active DNA demethylation. 5-hydroxymethyluracil methyl-CpG binding domain 4, DNA glycosylase Homo sapiens
2 MBD4 can excise the mismatched base paired with a guanine (G:X), where X is uracil, thymine or 5-hydroxymethyluracil (5hmU). 5-hydroxymethyluracil methyl-CpG binding domain 4, DNA glycosylase Homo sapiens
3 MBD4 can excise the mismatched base paired with a guanine (G:X), where X is uracil, thymine or 5-hydroxymethyluracil (5hmU). 5-hydroxymethyluracil methyl-CpG binding domain 4, DNA glycosylase Homo sapiens
4 MBD4 specifically recognizes the Watson-Crick polar edge of thymine or 5hmU via the O2, N3 and O4 atoms, thus restricting its activity to thymine/uracil-based modifications while excluding cytosine and its derivatives. 5-hydroxymethyluracil methyl-CpG binding domain 4, DNA glycosylase Homo sapiens
