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

nusBTranscription termination factor NusB; 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. (131 aa)    
Predicted Functional Partners:
nusG
Transcription antitermination factor; Participates in transcription elongation, termination and antitermination. Stimulates RNA polymerase pausing at U107 and U144 in the trp leader. NusG-stimulated pausing is sequence specific. Does not affect trp leader termination.
  
 
 0.999
folD
Methylenetetrahydrofolate dehydrogenase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
  
 0.996
rho
Transcriptional terminator Rho; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template.
  
  
 0.919
suhB
Inositol monophosphatase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the inositol monophosphatase superfamily.
   
 
 0.900
nusA
Transcription translation coupling factor involved in Rho-dependent transcription termination; Participates in both transcription termination and antitermination.
 
 
 0.876
guaC
GMP reductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides (Probable).
   
  
 0.875
greA
Transcription elongation factor; Necessary for efficient RNA polymerase transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by cleavage factors such as GreA or GreB allows the resumption of elongation from the new 3'terminus. GreA releases sequences of 2 to 3 nucleotides (By similarity); Belongs to the GreA/GreB family.
 
  
 0.861
pbuO
Hypoxanthine/guanine permease; Involved in the uptake of the purine bases hypoxanthine and guanine. May work at purine concentrations higher than 100 uM.
  
  
 0.857
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.
 
  
 0.834
rpsJ
Ribosomal protein S10 (BS13); Involved in the binding of tRNA to the ribosomes. Belongs to the universal ribosomal protein uS10 family.
   
 
 0.794
