title: Base eversion and shuffling by DNA methyltransferases.
abstract: The structures of two DNA cytosine methyltransferases reveal two novel methods of gaining access to the substrate cytosine residue, both of which involve eversion of the cytosine in a process that may require DNA bending. In one instance there is also widespread base shuffling and distortion of the DNA.
