title: DNA repair: bioinformatics helps reverse methylation damage.
abstract: Recent work has uncovered a novel DNA repair enzyme: the AlkB protein of Escherichia coli, which oxidises the methyl groups of 1-methyladenine and 3-methylcytosine to hydroxymethyl moieties; the oxidised groups are subsequently released as formaldehyde, regenerating the unmodified bases.
