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

Score
seqANegative modulator of initiation of replication; Negative regulator of replication initiation, which contributes to regulation of DNA replication and ensures that replication initiation occurs exactly once per chromosome per cell cycle. Binds to pairs of hemimethylated GATC sequences in the oriC region, thus preventing assembly of replication proteins and re- initiation at newly replicated origins. Repression is relieved when the region becomes fully methylated. Can also bind to hemimethylated GATC sequences outside of oriC region. Binds, with less affinity, to fully methylated GATC si [...] (181 aa)    
Predicted Functional Partners:
mukB
Chromosome condensin MukBEF, ATPase and DNA-binding subunit; Plays a central role in chromosome condensation, segregation and cell cycle progression. Functions as a homodimer, which is essential for chromosome partition. Involved in negative DNA supercoiling in vivo, and by this means organizes and compacts chromosomes. May achieve or facilitate chromosome segregation by condensation of DNA from both sides of a centrally located replisome during cell division. Stimulates both DNA relaxation and to a lesser extent decatenation activity of topoisomerase IV.

mutH
Methyl-directed mismatch repair protein; Sequence-specific endonuclease that cleaves unmethylated GATC sequences. It is involved in DNA mismatch repair.
  
   
 0.949
dnaA
Chromosomal replication initiator protein DnaA, DNA-binding transcriptional dual regulator; Plays a key role in the initiation and regulation of chromosomal replication. Binds in an ATP-dependent fashion to the origin of replication (oriC) to initiate formation of the DNA replication initiation complex exactly once per cell cycle. Binds the DnaA box (consensus sequence 5'-TTATC[CA]A[CA]A-3'); subsequent binding of DNA polymerase III subunits leads to replisome formation. The DnaA- ATP form converts to DnaA-ADP; once converted to ADP the protein cannot initiate replication, ensuring onl [...]

pgm
Phosphoglucomutase; This enzyme participates in both the breakdown and synthesis of glucose; Belongs to the phosphohexose mutase family.
 
    0.916
matP
Ter macrodomain organizer matS-binding protein; Required for spatial organization of the terminus region of the chromosome (Ter macrodomain) during the cell cycle. Prevents early segregation of duplicated Ter macrodomains during cell division. Binds specifically to matS, which is a 13 bp signature motif repeated within the Ter macrodomain; Belongs to the MatP family.
   
  
 0.912
hda
ATPase regulatory factor involved in DnaA inactivation; Mediates the interactions of DNA replication initiator protein DnaA with DNA polymerase subunit beta sliding clamp (dnaN). Stimulates hydrolysis of ATP-DnaA to ADP-DnaA, rendering DnaA inactive for reinitiation, a process called regulatory inhibition of DnaA or RIDA. ADP-binding activates Hda to hydrolyze DnaA-ATP; Hda monomers bind to ADP with about 200-fold greater affinity than for ATP. RIDA function can be genetically separated from viability, suggesting this protein has another function as well.
      
 0.912
slmA
Nucleoid occlusion factor, anti-FtsZ division inhibitor; Required for nucleoid occlusion (NO) phenomenon, which prevents Z-ring formation and cell division over the nucleoid. Acts as a DNA-associated cell division inhibitor that binds simultaneously chromosomal DNA and FtsZ, and disrupts the assembly of FtsZ polymers. SlmA-DNA-binding sequences (SBS) are dispersed on non-Ter regions of the chromosome, preventing FtsZ polymerization at these regions.
  
   
 0.867
dam
DNA adenine methyltransferase; Methylates DNA within the sequence GATC and protects the DNA from cleavage by the restriction endonuclease MboI. Although it shares sequence specificity with a number of type II restriction endonucleases and methylases, it is thought to act in postreplication mismatch repair rather than as a part of a restriction modification system. May also play a role in DNA replication.
  
  
 0.853
mioC
FMN-binding protein MioC; Probable electron transporter required for biotin synthase activity.
 
  
 0.845
yfbV
UPF0208 family inner membrane protein.
