3.C.1.1.1
Na+-transporting tetrahydromethanopterin S-methyltransferase (NMM), MtrABCDEFGH (Harms et al. 1995).  MtrA shows a short region of sequence similarity with MtrF; MtrB shows a shortregion of sezquence similarity with MtrG (all in their C-terminal TMSs). However, MtrC, D, E and H do not show noticable sequence similarity with other members of this system.
