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

topADNA 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 [...] (761 aa)    
Predicted Functional Partners:
MJ_1554
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 42.23; identified by sequence similarity; putative.
    
 0.959
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.
 
 0.958
leuS
leucyl-tRNA synthetase (leuS); Similar to SP:P26637 PID:1370340 PID:1403549 PID:3508 percent identity: 35.17; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.
   
 
 0.889
radB
DNA repair protein REC; Involved in DNA repair and in homologous recombination. May regulate the cleavage reactions of the branch-structured DNA. Has a very weak ATPase activity that is not stimulated by DNA. Binds DNA but does not promote DNA strands exchange (By similarity).
  
 0.862
radA
DNA 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.
  
 0.862
smc
Chromosome segretation protein (smc1); Required for chromosome condensation and partitioning. Belongs to the SMC family.
 
 
 0.852
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) [...]

MJ_1505
ATP dependent RNA helicase, putative; Similar to GB:Z47047 SP:P40562 PID:557851 PID:763347 percent identity: 31.59; identified by sequence similarity; putative.
   
 
 0.849
rad50
Purine NTPase; 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. Rad50 controls the balance between DNA end bridging and DNA resection via ATP-dependent structural rearrangements of the Rad50/Mre11 complex; Belongs to the SMC family. RAD50 subfamily.
 
 0.826
rpoD
DNA-directed RNA polymerase, subunit D (rpoD); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
