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 protein RAD51 (radA); Involved in DNA repair and in homologous recombination. Binds and assemble on single-stranded DNA to form a nucleoprotein filament. Hydrolyzes ATP in a ssDNA-dependent manner and promotes DNA strand exchange between homologous DNA molecules. (352 aa)    
Predicted Functional Partners:
pol
DNA polymerase B1; Similar to GB:D29671 PID:473967 PID:1620911 percent identity: 46.87; identified by sequence similarity; putative; Belongs to the DNA polymerase type-B family.
  
 0.962
pcn
Proliferating-cell nuclear antigen (pol30); Sliding clamp subunit that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase and other proteins to DNA during high-speed replication. Belongs to the PCNA family.
 
 0.944
rpa
Replication factor A related protein; Probably plays an essential for replication of the chromosome, DNA recombination and repair (By similarity). Binds approximately 20 nucleotides.
 
 0.943
nucS
Conserved hypothetical protein; Cleaves both 3' and 5' ssDNA extremities of branched DNA structures; Belongs to the NucS endonuclease family.
     
 0.939
hjc
Hypothetical protein; A structure-specific endonuclease that resolves Holliday junction (HJ) intermediates during genetic recombination. Cleaves 4-way DNA junctions introducing paired nicks in opposing strands, leaving a 5'-terminal phosphate and a 3'-terminal hydroxyl group that are ligated to produce recombinant products; Belongs to the Holliday junction resolvase Hjc family.
      
 0.927
fen
DNA repair protein RAD2 (rad2); Structure-specific nuclease with 5'-flap endonuclease and 5'- 3' exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Binds the unpaired 3'-DNA end and kinks the DNA to facilitate 5' cleavage specificity. Cleaves one nucleotide into the double-stranded DNA from the junction in flap DNA, leaving a nick for ligation. Also involved in the base excision repair (BER) [...]
  
 0.921
mre11
DNA repair protein RAD32 (rad32); Part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. The complex may facilitate opening of the processed DNA ends to aid in the recruitment of HerA and NurA. Mre11 binds to DSB ends and has both double-stranded 3'-5' exonuclease activity and single-stranded endonuclease activity.
  
 0.889
topA
DNA topoisomerase I (topA) {Bacillus subtilis; 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 stra [...]
  
 0.862
rnhB
Ribonuclease HII (rnhB); Endonuclease that specifically degrades the RNA of RNA-DNA hybrids; Belongs to the RNase HII family.
  
 
 0.857
MJ_1554
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 42.23; identified by sequence similarity; putative.
