2.A.4.7.3
Putative magnetosome membrane iron transporter, MamB.  Forms a heterodimeric stable complex with MamM which stabilizes MamB.  MamB also interacts with other proteins including the PDZ1 domain of MamE (Q6NE61).  Both MamB and MamM are essential for magnetite biomineralization and are involved in several steps in magnetosome formation, but only MamB is essential for formation of magnetosome membrane vesicles (Uebe et al. 2011).  Implicated in iron uptake due to homology with other CDF transporters.
