    Protein Summary

    This protein is likely a methytransferase, as evident by the bound SAM ligand and structural similarity to other methyltransferase. The SAM is well definied in one monomer but very low occ in the second monomer in the asu.

     

    Note from PFam:

    This protein didn't match any Pfam families. I have built a new Pfam entry from this sequence and it is called Methyltransf_17 (PF12692). This is the first structure for the family. I have added the family to the NADP_Rossmann clan (CL0063) for which there are already lots of structures known.
