| Enzyme Function |
FUNCTION: Plays 2 roles; promotes magnetite nucleation/formation and activates the MamE protease (By similarity) (PubMed:20674739). Despite its near conservation of a protease-like sequence, this is probably not a protease (By similarity). Required in conjunction with MamP for proteolysis of at least MamE, itself and MamP (By similarity). May transport a solute that controls MamE's protease activity. May place individual iron atoms into the magnetite lattice (By similarity). 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). {ECO:0000250|UniProtKB:Q2W8Q2, ECO:0000269|PubMed:20674739, ECO:0000269|PubMed:27286560}. |
