To DMT superfamily member RarD (Figure 5B) resulted in higher sequence similarity values (data not shown). As observed for SMR-BAT alignments (Figure 5A), the SMR fusion 'N-terminus regions' (TM1? and TM5?) showed the poorest TM domain alignments to Nterminus and central regions of DMT (TM1? and TM5?6) and MFS (TM1? and TM6?) sequences. It is important to note that the lack of TM domain alignabili
