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

dnaNDNA 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 of [...] (364 aa)    
Predicted Functional Partners:
dnaA
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. Belongs to the DnaA family.
 
 0.998
polA
DNA-directed DNA polymerase; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity.
 
 0.997
dinB_2
ImpB/MucB/SamB family protein; KEGG: ssr:SALIVB_0903 5.3e-162 dinB2; DNA polymerase IV 2 (Pol IV 2) K03502; Psort location: CytoplasmicMembrane, score: 8.16.
  
 0.991
dinB_1
ImpB/MucB/SamB family protein; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII.
  
 0.991
mutS_2
DNA mismatch repair protein MutS; This protein is involved in the repair of mismatches in DNA. It is possible that it carries out the mismatch recognition step. This protein has a weak ATPase activity.
  
 0.987
mutS_1
MutS domain V protein; KEGG: edi:EDI_294890 4.1e-23 DNA mismatch repair protein MSH2; Psort location: Cytoplasmic, score: 7.50.
  
 0.987
KXA29647.1
KEGG: amt:Amet_3057 1.3e-41 DNA polymerase III subunit delta; K02340 DNA polymerase III subunit delta.
 
 
 0.977
rnhB
Ribonuclease HII; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids.
  
 
 0.974
dnaX_2
DNA polymerase III, subunit gamma and tau; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity.
   
 0.972
dnaX_1
Hypothetical protein; KEGG: aoe:Clos_0062 1.8e-42 DNA polymerase III, delta prime subunit K02341; Psort location: Cytoplasmic, score: 9.97.
