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

addAATP-dependent deoxyribonuclease (subunit A); An essential component of the DNA double-stranded break repair machinery, the heterodimer acts as both an ATP-dependent DNA helicase and an ATP-dependent, dual-direction single-stranded exonuclease. Recognizes the B.subtilis chi site (5'-AGCGG-3') which transforms the enzyme from a helicase which degrades both DNA strands to one with only 5' -> 3' exonuclease activity. This generates a double-stranded DNA with a protruding 3'-terminated single-stranded tail suitable for the initiation of homologous recombination (chi fragment). The AddA nucl [...] (1232 aa)    
Predicted Functional Partners:
addB
ATP-dependent deoxyribonuclease (subunit B); The heterodimer acts as both an ATP-dependent DNA helicase and an ATP-dependent single-stranded exonuclease, acting in both directions. Recognizes the B.subtilis chi site (5'-AGCGG-3') which transforms the enzyme from a helicase which degrades both DNA strands to one with only 5' to 3' exonuclease activity. This generates a double-stranded DNA with a protruding 3'-terminated single-stranded tail suitable for the initiation of homologous recombination (chi fragment). The AddB nuclease domain is not required for chi fragment generation; this s [...]

sbcD
DNA repair exonuclease; SbcCD cleaves DNA hairpin structures. These structures can inhibit DNA replication and are intermediates in certain DNA recombination reactions. The complex acts as a 3'->5' double strand exonuclease that can open hairpins. It also has a 5' single-strand endonuclease activity (By similarity); Belongs to the SbcD family.

sbcC
DNA ATP-dependent repair enzyme; SbcCD cleaves DNA hairpin structures. These structures can inhibit DNA replication and are intermediates in certain DNA recombination reactions. The complex acts as a 3'->5' double strand exonuclease that can open hairpins. It also has a 5' single-strand endonuclease activity (By similarity); Belongs to the SMC family. SbcC subfamily.

recJ
Putative single-strand DNA-specific exonuclease; Putative single-stranded-DNA-specific exonuclease (By similarity). RecA thread formation during DNA double-strand break repair requires RecJ or AadAB; Belongs to the RecJ family.
     
 0.897
recF
DNA repair and genetic recombination factor; The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP. Is recruited to repair centers, foci that are the site of double- strand DNA break(s) after RecN and RecO; recruitment may depend on RecO.
      
 0.893
recQ
ATP-dependent DNA helicase; Probable DNA helicase. Required in synaptic and/or post- synaptic stages of recombination. Probably has overlapping function with RecQ (AC O34748). It probably acts to help generate ss-DNA from ds-DNA breaks.
  
  
 0.887
recN
Factor for double strand breaks DNA repair and genetic recombination; Involved in recombinational repair of damaged DNA. Seems to be the first protein recruited to repair centers, foci that are the site of double-strand DNA break(s), followed by RecO and then RecF.
  
  
 0.885
recD
Exodeoxyribonuclease V alpha chain; DNA-dependent ATPase and ATP-dependent 5'-3' DNA helicase. Has no activity on blunt DNA or DNA with 3'-overhangs, requires at least 10 bases of 5'-ssDNA for helicase activity; Belongs to the RecD family. RecD-like subfamily.
  
 
 0.877
recU
Holliday junction resolvase; Has at least 2 separable functions; Holliday junction resolution with generation of monomeric chromosomes, and modulation of RecA activity. Endonuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves mobile four-strand junctions by introducing symmetrical nicks in paired strands. Promotes annealing of linear ssDNA with homologous dsDNA. Required for DNA repair, homologous recombination and chromosome segregation. Partially inhibits the hydrolysis of dATP or rATP by RecA. Holliday junction resolution is stimulated by RuvB.
 
  
 0.834
recA
Multifunctional SOS repair factor; Multifunctional protein involved in homologous recombination, DNA repair and competence. Can catalyze the hydrolysis of (d)ATP in the presence of single-stranded DNA; prefers dATP at least in vitro, catalyzes the dATP-dependent uptake of single- stranded DNA by duplex DNA, and the dATP-dependent hybridization of homologous single-stranded DNAs (strand exchange). RecA-ATP cannot catalyze homologous DNA strand exchange; SsbA and DprA activate strand exchange by RecA-ATP. It interacts with LexA causing its activation and leading to its autocatalytic clea [...]
