Enzyme Function |
FUNCTION: Plays 2 roles; promotes magnetite nucleation/formation and activates the MamE protease (Probable). Despite its near conservation of a protease-like sequence, this is probably not a protease (PubMed:26981620) (Probable). Required in conjunction with MamP for proteolysis of at least MamE, itself and MamP (PubMed:26981620). May transport a solute that controls MamE's protease activity. May place individual iron atoms into the magnetite lattice (Probable). {ECO:0000269|PubMed:26981620, ECO:0000305|PubMed:20212111, ECO:0000305|PubMed:21414040, ECO:0000305|PubMed:26981620}. |
