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

PP_3831Homologs of previously reported genes of unknown function. (340 aa)    
Predicted Functional Partners:
ligD
DNA ligase D; Function of homologous gene experimentally demonstrated in an other organism; enzyme; DNAmetabolism : DNA replication, recombination, and repair.
 
 
 0.827
recQ
ATP-dependent DNA 3' to 5' helicase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; DNA metabolism.
    
 
 0.781
gyrB
DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
   
 
 0.752
parE
DNA topoisomerase IV subunit B; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule; Belongs to the type II topoisomerase family. ParE type 1 subfamily.
   
 
 0.752
ku
Non-homologous end joining protein; With LigD forms a non-homologous end joining (NHEJ) DNA repair enzyme, which repairs dsDNA breaks with reduced fidelity. Binds linear dsDNA with 5'- and 3'- overhangs but not closed circular dsDNA nor ssDNA. Recruits and stimulates the ligase activity of LigD. Belongs to the prokaryotic Ku family.
 
    0.740
PP_1105
Putative DNA ligase, ATP-dependent; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology.
 
 
 
 0.702
rnhB
Ribonuclease HII; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids; Belongs to the RNase HII family.
    
 
 0.683
PP_3266
Homologs of previously reported genes of unknown function.
  
    0.645
modA
Molybdate-binding periplasmic protein.
       0.645
modB
Molybdenum transport system permease protein ModB; Part of the binding-protein-dependent transport system for molybdenum; probably responsible for the translocation of the substrate across the membrane; Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily.
       0.645
