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

nusBN utilization substance protein B; Involved in transcription antitermination. Required for transcription of ribosomal RNA (rRNA) genes. Binds specifically to the boxA antiterminator sequence of the ribosomal RNA (rrn) operons. (141 aa)    
Predicted Functional Partners:
ribH
6,7-dimethyl-8-ribityllumazine synthase; Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2- butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin.
  
  
 0.971
rpsJ
30S ribosomal protein S10; Involved in the binding of tRNA to the ribosomes. Belongs to the universal ribosomal protein uS10 family.
   
 
 0.964
fmt
methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
  
  
 0.851
nusA
Transcription termination protein NusA; Participates in both transcription termination and antitermination.
  
 
 0.774
RibD
Riboflavin biosynthesis protein RibD; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.
  
  
 0.747
ribB
3,4-dihydroxy-2-butanone-4-phosphate synthase; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; Belongs to the DHBP synthase family.
   
 
 0.739
rpoZ
DNA-directed RNA polymerase subunit omega; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
  
 
 0.719
folD
Bifunctional methylenetetrahydrofolate dehydrogenase/methenyltetrahydrofolate cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
  
 0.653
nusG
Transcription termination/antitermination protein NusG; Participates in transcription elongation, termination and antitermination.
  
 
 0.641
topA
DNA topoisomerase I; 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 supe [...]
