hydroxymethylated DNA binding activities of wild-type and mutant enzymes, the enzyme undergoes a conformational change from a substrate-free open form to a closed substrate-binding form stabilized by several salt bridges and probably involving Ser106 and Glu22 |

2.4.1.26 | UDP-glucose + hydroxymethylated DNA |
Glu22 seems not to be responsible for activation of the nucleophilic attack, Ser106 and Glu311 probably form a salt bridge in the closed enzyme formation, Glu311 is probably involved in interaction with UDP-glucose, Arg236, Arg256 and Met231 are probably involved in interaction with the DNA |

extent of glucosylation varies between 50% and 80% of the amount of hydroxymethylcytosine residues calculated to be present, T4 DNA with no unsubstituted hydroxymethylcytosine groups does not serve as acceptor, T2 DNA: no activity with enzyme from T2-infected cells, small activity with enzyme from T4- and T6-infected cells |
