Dethiomethylation
WebDethiomethylation as an alternative repair pathway The in vitro as well as the in vivo analyses of AlkB convinced us of the role of AlkB as key player in ms 2 C demethylation. Based on our data shown in Fig. 4 , we assume direct demethylation by AlkB, which results in the recovery of [ 32 S]-s 2 C.
