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

EAR12154.1
Hypothetical protein; COG0251 Putative translation initiation inhibitor, yjgF family.
  
 0.999
nusA
Transcription elongation factor NusA; Participates in both transcription termination and antitermination.
 
   0.997
rplK
50S ribosomal protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
 
 0.993
rplL
50S ribosomal protein L7/L12; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors. Is thus essential for accurate translation; Belongs to the bacterial ribosomal protein bL12 family.
 
 0.993
mfd
Transcription-repair coupling factor; Couples transcription and DNA repair by recognizing RNA polymerase (RNAP) stalled at DNA lesions. Mediates ATP-dependent release of RNAP and its truncated transcript from the DNA, and recruitment of nucleotide excision repair machinery to the damaged site; In the C-terminal section; belongs to the helicase family. RecG subfamily.
  
 
 
 0.989
nusG
Putative transcription antitermination protein; Participates in transcription elongation, termination and antitermination.
 
 
 0.986
EAR13889.1
COG1508 DNA-directed RNA polymerase specialized sigma subunit, sigma54 homolog.
  
 
 
 0.985
rplA
50S ribosomal protein L1; Binds directly to 23S rRNA. The L1 stalk is quite mobile in the ribosome, and is involved in E site tRNA release.
