| amb0958 | mms6 | amb0958 | amb0956 | Uncharacterized protein; Conserved in bacteria. | Bacterial magnetic particle specific iron-binding protein; Promotes the formation of magnetite in Fe(2+)-rich conditions, when magnetite is not readily formed. Binds Fe(3+) and Fe(2+) (Probable). May play a role in nucleation of magnetite crystal formation (Probable). May help control production of crystals with a specific morphology (Probable). Greatly improves the formation of magnetosome-like magnetite crystals in vitro. Isolated short protein, probably residues 75-133, binds up to 18 Fe(3+) per monomer and self-assembles into micelles about 21-26 nm in diameter; the C-terminal 21 [...] | 0.626 |
| amb0958 | mmsF | amb0958 | amb0957 | Uncharacterized protein; Conserved in bacteria. | Hypothetical protein; Plays a major role in synthesis of cubooctahedral magnetite crystals by controlling crystal growth and morphology after nucleation. Has a partially redundant function with MamF (By similarity). When overexpressed in E.coli the soluble protein self assembles into shells of about 36 nm. This protein mediates the formation of magnetite nanoparticles from a solution of Fe(2+) and Fe(3+) sulfate; the crystals are larger and lack alternative iron oxide/oxyhydroxide species seen in the protein's absence. | 0.773 |

| ftsZ | mamE | amb1015 | amb0963 | Cell division GTPase; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity. | Trypsin-like serine protease, typically periplasmic; Acts at 2 distinct steps of magnetosome formation; required for correct localization of proteins to the magnetosome while the protease activity is required for maturation of small magnetite crystals into larger, functional ones. The 2 functions are separable by mutation. Probably cleaves at least itself, MamO and MamP; cleavage requires the putative transport domain of MamO (Probable). Involved in localization of some proteins (at least MamA, MamC, MamF, MamI and MamJ) to the magnetosome. | 0.406 |

Binds GTP and shows GTPase activity. | Actin-like ATPase; Protein with ATPase activity which forms dynamic cytoplasmic filaments (probably with paralog MamK-like) that organize magnetosomes into long chains running parallel to the long axis of the cell (Probable). Turnover of MamK filaments is probably promoted by MamK-like, which provides a monomer pool. Forms twisted filaments in the presence of ATP or GTP. Serves to close gaps between magnetosomes in the chain. Interaction with MCP10 is involved in controlling the response to magnetic fields, possibly by controlling flagellar rotation.
