FIG. 2.
Alignment of CmuC from IMB-1, CmuC from H. chloromethanicum CM2, CmuC from M. chloromethanicum CM4, and MtaA from M. barkeri. CmuC from IMB-1 has been aligned with CmuC from H. chloromethanicum CM2 (AF281259), CmuC from M. chloromethanicum CM4 (AJ011316), and MtaA from M. barkeri. Similar residues are shaded in gray; identical residues are in black boxes. The putative zinc-binding motif identified in MtbA from M. barkeri is shown in boldface type below the alignment (14).
