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

radADNA repair: sensitivity to gamma and UV radiation; Plays a role in repairing double-strand DNA breaks, probably involving stabilizing or processing branched DNA or blocked replication forks (By similarity). Required for efficient transformation with chromosomal (linear) DNA, but not for replicative plasmid DNA. Its increased sensitivity to a DNA damaging agent suggests it may be required for DNA repair. (420 aa)    
Predicted Functional Partners:
recA
DNA recombination/repair; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs (By similarity). It interacts with LexA causing its activation and leading to its autocatalytic cleavage (By similarity). Required for DNA transformation; protects transforming DNA from degradation, possibly in combination with DprA. Present at 15,000-30,000 monomers per competent cell.

recG
Branch migration of Holliday junctions, junction-specific DNA helicase; Critical role in recombination and DNA repair. Helps process Holliday junction intermediates to mature products by catalyzing branch migration. Has a DNA unwinding activity characteristic of a DNA helicase with a 3'- to 5'- polarity. Unwinds branched duplex DNA (Y- DNA); Belongs to the helicase family. RecG subfamily.
      
 0.875
recX
Conserved hypothetical protein; Modulates RecA activity; Belongs to the RecX family.
  
  
 0.867
recJ
Single-stranded DNA-specific exonuclease, 5'-3'.
 
  
 0.847
dut
Deoxyuridinetriphosphatase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA.
  
  
 0.829
ruvB
Branch migration of Holliday structures; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing.

ruvA
Holliday junction DNA helicase; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing. RuvA stimulates, in the presence of DNA, the weak ATPase activity of RuvB.
  
  
 0.712
smf
DNA processing Smf protein; Protein that helps load RecA onto ssDNA during transformation. Required for DNA transformation. Not required for DNA uptake but for a later stage of transformation. Thought to interact at the cell pole with newly imported transforming ssDNA which it binds cooperatively, protecting linear and circular ssDNA from nuclease action. Forms bridges between DNA segments. Favors the loading of RecA onto ssDNA and formation of RecA-DNA filaments, triggering RecA- catalysis of ATP-driven homologous DNA pairing. Belongs to the DprA/Smf family.
