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

spoIIIESpore DNA translocase; Plays an essential role during sporulation. Required for the translocation of the chromosomal DNA from mother cell into the forespore during polar septation, for the final steps of compartmentalization in the presence of trapped DNA, and for the final steps of engulfment. The N-terminus mediates localization to the division septum and is required for both septal membrane fusion and engulfment membrane fusion. May form DNA-conducting channels across the two lipid bilayers of the septum after cell division. The C-terminus functions as a DNA motor that exports DNA i [...] (787 aa)    
Predicted Functional Partners:
ftsA
Cell-division protein essential fo Z-ring assembly; Cell division protein that is required for the assembly of the Z ring. May serve as a membrane anchor for the Z ring (By similarity). Binds and hydrolyzes ATP. Also involved in sporulation (Probable). Belongs to the FtsA/MreB family.
  
  
 0.997
ftsZ
Cell-division initiation protein; 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.
   
 
 0.990
ftsW
Cell-division protein; Peptidoglycan polymerase that is essential for cell division.
 
  
 0.989
ftsE
Cell-division ABC transporter (ATP-binding protein); Part of the ABC transporter FtsEX involved in sporulation. May act as an importer, possibly at the top of a hierarchical cascade leading to the correct temporal initiation of sporulation. Acts upstream of the histidine kinases KinA, KinB and KinC, the RapA phosphatase and the Spo0A sporulation protein.
   
  
 0.975
parB
Site-specific DNA-binding protein; Required for the initiation of sporulation and for normal chromosome segregation. Antagonizes sporulation inhibition by Soj. It probably interacts with a specific DNA site and other proteins involved in partitioning and cell division, and antagonizes Soj in response to cell cycle events related to chromosome partitioning.
  
  
 0.972
codV
Site-specific tyrosine recombinase for chromosome partitioning; Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. The XerC- XerD complex is essential to convert dimers of the bacterial chromosome into monomers to permit their segregation at cell division. It also contributes to the segregational stability of plasmids.
 
   
 0.965
ripX
Site-specific tyrosine recombinase for chromosome partitioning; Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. The XerC- XerD complex is essential to convert dimers of the bacterial chromosome into monomers to permit their segregation at cell division. It also contributes to the segregational stability of plasmids.
  
   
 0.963
yshA
Conserved hypothetical protein; Activator of cell division through the inhibition of FtsZ GTPase activity, therefore promoting FtsZ assembly into bundles of protofilaments necessary for the formation of the division Z ring. It is recruited early at mid-cell but it is not essential for cell division (By similarity); Belongs to the ZapA family. Type 2 subfamily.
   
  
 0.959
yukE
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 15576783.
  
 
 0.886
parA
Chromosome partitioning protein; Inhibits the initiation of sporulation, Spo0J antagonizes this inhibition. Soj ultimately inhibits the activation (phosphorylation) of Spo0A; Belongs to the ParA family.
