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

polXDNA polymerase/3'-5' exonuclease X; Strictly DNA-template-directed DNA polymerase, preferentially acting on DNA structures containing gaps from one to a few nucleotides and bearing a phosphate group at the 5' end of the downstream DNA. The fact that PolX is able to conduct filling of a single-nucleotide gap, allowing further sealing of the resulting nick by a DNA ligase, points to a putative role in base excision repair (BER) during the B.subtilis life cycle. Moreover, also possesses a 3'-5' exonuclease activity able to edit unpaired 3'-termini in a gapped DNA substrate and likely invo [...] (570 aa)    
Predicted Functional Partners:
ykoU
ATP-dependent DNA ligase subunit; With Ku forms a non-homologous end joining (NHEJ) DNA repair enzyme, which repairs dsDNA breaks with reduced fidelity (Probable). Probably involved in DNA repair during spore germination. In the N-terminal section; belongs to the LigD polymerase family.
  
 0.968
mutSB
Putative DNA mismatch repair enzyme; Endonuclease that is involved in the suppression of homologous recombination and may therefore have a key role in the control of bacterial genetic diversity; Belongs to the DNA mismatch repair MutS family. MutS2 subfamily.
  
  
 0.965
yshE
Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
  
  
 0.945
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity.
  
 0.921
exoA
Apurinic/apyrimidinic endonuclease; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
   
 0.898
nfo
Type IV apurinic/apyrimidinic endonuclease; Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic (AP) sites, generating a 3'-hydroxyl group and a 5'-terminal sugar phosphate.
   
  
 0.897
polC
DNA polymerase III (alpha subunit); Required for replicative DNA synthesis. This DNA polymerase also exhibits 3' to 5' exonuclease activity; Belongs to the DNA polymerase type-C family. PolC subfamily.
   
  
 0.861
yshB
Putative integral membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
  
  
 0.861
ligB
Bacteriophage SPbeta DNA ligase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type h: extrachromosomal origin; Belongs to the ATP-dependent DNA ligase family.
 
 0.808
ypcP
5'3'-exonuclease; 5'-3' exonuclease acting preferentially on double-stranded DNA.
   
 0.712
