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

Score
hfqHost factor 1 protein, putative; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family. (77 aa)    
Predicted Functional Partners:
miaA
tRNA delta(2)-isopentenylpyrophosphate transferase; Catalyzes the transfer of a dimethylallyl group onto the adenine at position 37 in tRNAs that read codons beginning with uridine, leading to the formation of N6-(dimethylallyl)adenosine (i(6)A); Belongs to the IPP transferase family.
  
  
 0.963
pnp
Polyribonucleotide nucleotidyltransferase, putative; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
    
 
 0.956
ABD30379.1
Hydrolase, alpha/beta fold family domain protein.
       0.818
katA
Catalase; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide. Involved in resistance to paraquat when fur is absent and to tert-butyl hydroperoxide. Is important for survival under glucose starvation and desiccation conditions. Not required for virulence although is necessary for nasal colonization.
    
 
 0.789
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.
   
 
 0.769
glpD
Conserved hypothetical protein; Belongs to the FAD-dependent glycerol-3-phosphate dehydrogenase family.
     
 0.768
ptsG
PTS system, glucose-specific component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in glucose transport.
   
  
 0.710
ABD30559.1
Conserved hypothetical protein.
    
 
 0.707
rnr
Ribonuclease R, putative; 3'-5' exoribonuclease that releases 5'-nucleoside monophosphates and is involved in maturation of structured RNAs.
 
 
 
 0.698
clpX
ATP-dependent Clp protease, ATP-binding subunit ClpX; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP.
