9.B.90 The Putative Channel Forming 2 TMSs MamC (MamC) Family
The MamC family consists of magnetosome-associated orthologues, some of which are designated 'tightly bound bacterial magnetic particle protein'. It may play a role in iron transport with the magnetosome (Scheffel et al., 2008). Homologues (120-130aas; 2TMSs) are found in a variety of Gram-negative α-proteobacteria, with and without magnetosomes. They show limited sequence similarity with portions of A+G-rich animal elastins (EAW69628).
