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

parAChromosome partitioning protein; Inhibits the initiation of sporulation, Spo0J antagonizes this inhibition. Soj ultimately inhibits the activation (phosphorylation) of Spo0A; Belongs to the ParA family. (253 aa)    
Predicted Functional Partners:
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.

dnaA
Chromosomal replication initiator protein DnaA; Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'- TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids. DnaA can inhibit its own gene expression as well as that of other genes.

noc
DNA-binding protein Spo0J-like; Effects nucleoid occlusion by binding relatively nonspecifically to DNA and preventing the assembly of the division machinery in the vicinity of the nucleoid, especially under conditions that disturb the cell cycle. It helps to coordinate cell division and chromosome segregation by preventing the formation of the Z ring through the nucleoid, which would cause chromosome breakage.
 
 0.990
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.
  
  
 0.907
smc
Chromosome condensation and segregation SMC ATPase; Required for chromosome condensation and partitioning. Belongs to the SMC family.
  
  
 0.902
spoIIIE
Spore 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 [...]

racA
Chromosome-anchoring protein RacA; Required for the formation of axial filaments and for anchoring the origin regions at the cell poles in sporulating cells, thus ensuring proper chromosome segregation in the prespore. Binds in a dispersed manner throughout the chromosome but preferentially to sites clustered in the origin portion of the chromosome, causing condensation of the chromosome and its remodeling into an elongated, anchored structure; Belongs to the RacA family.
   
  
 0.860
pcfA
Factor controlling DNA replication; Inhibits DNA replication in growing cells, thus reducing chromosome copy number and playing a significant role during the onset of sporulation.
      
 0.845
dnaD
DNA-remodelling primosomal protein; Probable component of primosome involved in the initiation of DNA replication.
     
 0.837
dnaN
DNA polymerase III (beta subunit); Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation o [...]
