Stereoview ribbon diagrams of superimposed structures of the MTase 1 domain (green), VP39 (blue) and RrmJ (magenta). MTase 1 shows elaborations of the common fold similar to those of VP39, which are altogether absent from the RrmJ structure and which are predicted to take part in cap recognition and binding. AdoMet (copied from the RrmJ structure) and the K-D-K-E tetrad of putative catalytic residues are shown in wireframe representation.
