5-Hydroxymethyluracil
5-Hydroxymethyluracil (5hmU), also known as alpha-hydroxythymine, belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5hmU has been identified as a thymine base modification found in the genomes of a diverse range of organisms (PMID: 28137275). 5-hydroxymethyluracil has been detected in bacteriophages, dinoflagellates, leishmania, and in eukaryotic genomes where its level appears to be cell type-specific. 5-Hydroxymethyluracil arises from the oxidation of thymine. 5-Hydroxymethyluracil is produced by the enzyme thymine dioxygenase (EC 1.14.11.6) which catalyzes the chemical reaction thymine + 2-oxoglutarate + O2 <-> 5-hydroxymethyluracil + succinate + CO2. The 3 substrates of this enzyme are thymine, 2-oxoglutarate, and O2, whereas its 3 products are 5-hydroxymethyluracil, succinate, and CO2. The 5hmU base can also be generated by oxidation/hydroxylation of thymine by the Ten-Eleven-Translocation (TET) proteins or result from deamination of 5hmC (PMID: 29184924). DNA containing 5hmU has been reported to be more flexible and hydrophilic (PMID: 29184924). 5-Hydroxymethyluracil is an oxidation damage product derived from thymine or 5-methylcytosine. It is a product of thymine dioxygenase [EC 1.14.11.6].
