Function

MAMM_MAGGM Essential for magnetosome formation; required for stable accumulation of MamB (PubMed:22007638). May nucleate iron crystal formation (Probable). Probably binds and transports iron. Binds divalent cations, possibly up to 3 Zn(2+) per dimer in vitro, probably iron in vivo (Probable) (PubMed:30811856). One of 7 genes (mamLQBIEMO) able to induce magnetosome membrane biogenesis; coexpression of mamLQRBIEMO in a deletion of the 17 gene mamAB operon restores magnetosome vesicle formation but not magnetite biosynthesis (PubMed:27286560).^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Publication Abstract from PubMed

Cation diffusion facilitators (CDF) are part of a highly conserved protein family that maintains cellular divalent cation homeostasis in all domains of life. CDF's were shown to be involved in several human diseases, such as Type-II diabetes and neurodegenerative diseases. In this work, we employed a multi-disciplinary approach to study the activation mechanism of the CDF protein family. For this we used MamM, one of the main ion transporters of magnetosomes - bacterial organelles that enable magnetotactic bacteria to orientate along geomagnetic fields. Our results reveal that the cytosolic domain of MamM forms a stable dimer that undergoes distinct conformational changes upon divalent cation binding. MamM conformational change is associated with three metal binding sites that were identified and characterized. Altogether, our results provide a novel auto-regulation mode of action model in which the cytosolic domain's conformational changes upon ligand binding allows the priming of the CDF into its transport mode.

Cation diffusion facilitators transport initiation and regulation is mediated by cation induced conformational changes of the cytoplasmic domain.,Zeytuni N, Uebe R, Maes M, Davidov G, Baram M, Raschdorf O, Nadav-Tsubery M, Kolusheva S, Bitton R, Goobes G, Friedler A, Miller Y, Schuler D, Zarivach R PLoS One. 2014 Mar 21;9(3):e92141. doi: 10.1371/journal.pone.0092141. eCollection, 2014.
