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.

proQActivator of proP; RNA chaperone with significant RNA binding, RNA strand exchange and RNA duplexing activities. May regulate ProP activity through an RNA-based, post-transcriptional mechanism. Belongs to the ProQ family. (228 aa)    
Predicted Functional Partners:
hfq
Host factor I for bacteriophage Q beta replication; 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 (By similarity). Plays a central regulatory role in the microbial response to space flight conditions. Is essential for virulence and is required for efficient invasion of non-phagocytic cells.
   
  
 0.971
csrA
Carbon storage regulator; A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability. Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems. Usually binds in the 5'-UTR; binding at or near the Shine-Dalgarno sequence prevents ribosome-binding, repressing translation, binding elsewhere in the 5'-UTR can activate translation and/or stabilize the mRNA. Its function is antagonized by small RNA(s).
   
  
 0.964
prc
Carboxy-terminal protease for penicillin-binding protein 3; Involved in the cleavage of a C-terminal peptide of 11 residues from the precursor form of penicillin-binding protein 3 (PBP3). May be involved in protection of the bacterium from thermal and osmotic stresses (By similarity).
 
  
 0.930
rne
RNase E; Endoribonuclease that plays a central role in RNA processing and decay. Required for the maturation of 5S and 16S rRNAs and the majority of tRNAs. Also involved in the degradation of most mRNAs. Belongs to the RNase E/G family. RNase E subfamily.
   
  
 0.919
yebR
Putative GAF domain-containing protein; Similar to E. coli orf, hypothetical protein (AAC74902.1); Blastp hit to AAC74902.1 (183 aa), 83% identity in aa 11 - 183.
 
  
 0.910
rnc
RNase III, ds RNA; Digests double-stranded RNA. Involved in the processing of ribosomal RNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Removes small helical intervening sequences (IVSs) from all 7 of the 23S rRNA transcripts. Probably also processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Probably processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism.
   
  
 0.903
cspE
RNA chaperone, negative regulator of cspA transcription; Similar to E. coli cold shock protein (AAC73724.1); Blastp hit to AAC73724.1 (69 aa), 98% identity in aa 1 - 69.
   
  
 0.881
hupA
DNA-binding protein HU-alpha; Histone-like DNA-binding protein which is capable of wrapping DNA to stabilize it, and thus to prevent its denaturation under extreme environmental conditions; Belongs to the bacterial histone-like protein family.
   
  
 0.878
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.
   
  
 0.875
rnb
RNase II; Involved in mRNA degradation. Hydrolyzes single-stranded polyribonucleotides processively in the 3' to 5' direction.
