2.A.1.43.2
The magnetosome permease fused to a C-terminal YedZ-like domain, MamZ (von Rozycki et al., 2004). This protein has 649 aas and 18 TMSs with a C-terminal YedZ domain and is therefore in the YedZ superfamily as well as the MFS. The two MFS proteins in the magnetosome membrane, MamZ and MamH (44% identical to MamZ), appear to overlap in function as deletion of their two genes have additive effects (Raschdorf et al. 2013). Magnetosome biogenesis has been reviewed ().
