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

mamJPeriplasmic protein TonB; Regulates the dynamic behavior of MamK filaments; paralog LimJ also promotes MamK turnover. At least one other protein besides MamJ and LimJ is required for MamK turnover. May connect magnetosomes to MamK filaments (Probable). Moves from the cell poles towards midcell; movement does not depend on the treadmilling ability of MamK, suggesting MamJ associates and disassociates continuously from the MamK filament (By similarity). (506 aa)    
Predicted Functional Partners:
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 [...]

mamI
Hypothetical protein; Essential for magnetosome formation. May bind magnetite (Probable). May be involved in an early stage of magnetosome nucleation (By similarity).
     
 0.814
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.
     
 0.814
mamH
Permease of the major facilitator superfamily; Required for correct biomineralization of the magnetosome; probably transports some form of iron. Partially functionally redundant with MamZ; Belongs to the major facilitator superfamily.
       0.618
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.
     
 0.583
mms24
TPR repeat; Probably forms a large homooligomer on which other magnetosome subunits assemble (Probable). Required for formation of functional magnetosomes from pre-existing vesicles, it has a dynamic location in the cell.
     
 0.509
mamL
Hypothetical protein; Essential for magnetosome formation. Belongs to the magnetosome MamL family.

rplX
Ribosomal protein L24; One of two assembly initiator proteins, it binds directly to the 5'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit.
  
     0.456
rplD
Ribosomal protein L4; One of the primary rRNA binding proteins, this protein initially binds near the 5'-end of the 23S rRNA. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome.
