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

top6BDNA topoisomerase VI, subunit B; Relaxes both positive and negative superturns and exhibits a strong decatenase activity. (662 aa)    
Predicted Functional Partners:
top6A
DNA topoisomerase VI, subunit A; Relaxes both positive and negative superturns and exhibits a strong decatenase activity; Belongs to the TOP6A family.

pheT
Phenylalanyl-tRNA synthetase, beta subunit; Function of strongly homologous gene; enzyme.
  
     0.593
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.
 
  
 0.572
NIDE2075
Protein of unknown function; No homology to any previously reported sequences.
       0.562
pheS
Phenylalanyl-tRNA synthetase, alpha subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 2 subfamily.
  
     0.555
NIDE2076
Exported protein of unknown function; No homology to any previously reported sequences.
