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

mamFHypothetical protein; Plays a role in regulating magnetite crystal size; partially redundant function with MmsF. (111 aa)    
Predicted Functional Partners:
mamG
Bacterial magnetic particle specificiron-binding protein; Plays a role in regulating magnetite crystal size. Belongs to the magnetosome MamG (TC 9.B.95) protein family.
     
 0.832
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).
     
 0.825
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.
     
 0.821
mms6
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 [...]

Permease.

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.

mms5
Cell wall protein TIR3 precursor; Might be involved in magnetite crystal growth.
      
 0.444
amb0955
Hypothetical protein.
       0.443
mamO
Trypsin-like serine protease; 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 (Probable). Required in conjunction with MamP for proteolysis of at least MamE, itself and MamP. May transport a solute that controls MamE's protease activity. May place individual iron atoms into the magnetite lattice (Probable). In the N-terminal section; belongs to the peptidase S1C family.
