ENZYME entry: EC 1.14.11.n2
| Accepted Name |
|---|
| methylcytosine dioxygenase.
|
| Reaction catalysed |
|---|
| 2-oxoglutarate + a 5-methyl-2'-deoxycytidine in DNA + O2 <=> a 5-hydroxymethyl-2'-deoxycytidine in DNA + CO2 + succinate |
| Comment(s) |
|---|
- Dioxygenase that catalyzes the conversion of the modified genomic
base 5-methylcytosine (5mC) into 5-hydroxymethylcytosine (5hmC).
- Might initiate a process leading to cytosine demethylation through
deamination into 5-hydroxymethyluracil (5hmU) and subsequent
replacement by unmethylated cytosine by the base excision repair
system.
- Methylation at the C5 position of cytosine bases is an epigenetic
modification of the mammalian genome which plays an important role in
transcriptional regulation.
