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

pnpPolyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. (712 aa)    
Predicted Functional Partners:
cshA
ATP-dependent RNA helicase; DEAD-box RNA helicase possibly involved in RNA degradation. May work in conjunction with the cold shock proteins to ensure proper initiation of transcription at low and optimal temperatures. Unwinds dsRNA in both 5'- and 3'-directions and shows RNA-dependent ATPase activity (By similarity). Probably has a somewhat redundant function with cshB, as cshA can partially complement the growth effects of a cshB deletion. Plays a role in adaptation to cold, oxididant and pH stress.
  
 
 0.991
nusA
N utilization substance protein A; Participates in both transcription termination and antitermination.
 
  
 0.977
rho
Transcription termination factor 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.
  
  
 0.968
rny
Hydrolase (HAD superfamily); Endoribonuclease that initiates mRNA decay. Belongs to the RNase Y family.
  
 
 0.967
pyrG
CTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
  
  
 0.952
infB
Bacterial Protein Translation Initiation Factor 2 (IF-2); One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. IF-2 subfamily.
  
  
 0.921
rpoB
DNA-directed RNA polymerase beta chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
  
 0.917
BC_4439
Ribonuclease G.
  
 
 0.917
rplC
LSU ribosomal protein L3P; One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit; Belongs to the universal ribosomal protein uL3 family.
  
  
 0.913
rpsO
SSU ribosomal protein S15P; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it helps nucleate assembly of the platform of the 30S subunit by binding and bridging several RNA helices of the 16S rRNA.
