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

ssbBSingle-strand DNA-binding protein; Not essential for replication of the chromosome, but is required for optimal competence. Binds ssDNA, binding is facilitated by DprA, acts as an accessory factor for homologous DNA strand exchange. (113 aa)    
Predicted Functional Partners:
dprA
DNA processing Smf single strand binding protein; Protein that helps load RecA onto ssDNA during transformation. Binds cooperatively to circular ssDNA, is able to bridge different segments of DNA. Favors the loading of RecA onto SsbA- or SsbB-coated ssDNA and formation of RecA-DNA filaments. RecA-ATP cannot catalyze homologous DNA strand exchange; SsbA and DprA activate strand exchange by RecA-ATP.

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 [...]

coiA
Protein involved in establishment of DNA transport in competence; Required for optimal transformation.
   
  
 0.981
comFA
Helicase competence protein; Involved in transformation (competence for DNA uptake). Required for DNA uptake but not for binding. May provide the driving force for transport of DNA through an aqueous channel. Belongs to the helicase family.
   
  
 0.980
comGA
Membrane associated ATPase for DNA competence; Required for uptake of DNA by competent cells.
  
  
 0.972
comEA
Membrane bound high-affinity DNA-binding receptor; Needed for both DNA binding and transport. It is absolutely required for the uptake of transforming DNA but not for binding. Its role in binding may be indirect.
  
  
 0.961
topB
DNA topoisomerase III; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA su [...]

comEC
DNA channel for uptake in competent cells; The comE operon is required for the binding and uptake of transforming DNA. ComEC is required for internalization but is dispensable for DNA binding; To H.influenzae REC2, N.gonorrhoeae ComA and E.coli YcaI.

recO
DNA double strand break repair and homologous recombination factor; Plays a role in DNA double-stranded break repair. It seems to be involved in an RecBC-independent recombinational process of DNA repair. It may act with RecF and RecR. Is recruited to repair centers, foci that are the site of double-strand break(s) after RecN and before RecF; may actively recruit RecF.
