B12-binding domain/radical SAM domain protein, MJ_0865 family
Members of this family have both a B12 binding homology domain (pfam02310) and a radical SAM domain (pfam04055), and occur only once per genome. This protein occurs so far only in methanogenic archaea. Some species with members of this family have a related protein with similar domain architecture (see TIGR04013).
