STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

mms6Bacterial 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 [...] (157 aa)    
Predicted Functional Partners:
mmsF
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.

mms13
Tightly bound bacterial magnetic particle protein; Probably involved in magnetite crystal growth (Probable). The lumenal domain may bind the magnetite crystals, affecting crystal size and shape (Probable).
     
 0.718
mms7
Tightly bound bacterial magnetic particle protein; Helps regulate magnetite crystal morphology, probably in a single growth axis. May help control oxido-reduction reactions surrounding the crystal lattice of the forming magnetite mineral (Probable). Probably binds Fe(2+), may play a role in nucleation of magnetite crystal formation (Probable). Expression in a deletion mutant restores growth of spherical (wild-type) magnetite crystals. Increased protein levels allow crystal growth in the minor axis but not increased numbers of crystals.

mamF
Hypothetical protein; Plays a role in regulating magnetite crystal size; partially redundant function with MmsF.

ftsZ
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.
      
 0.616
mamK
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. Expression in E.coli yields a filam [...]
      
 0.603
mamE
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.
      
 0.598
mamM
Predicted Co/Zn/Cd cation transporters; Probably plays a role in biomineralization (Probable). Required for stable accumulation of MamB (By similarity). Probably binds and transports iron. May nucleate iron crystal formation (By similarity); Belongs to the cation diffusion facilitator (CDF) transporter (TC 2.A.4) family.
