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:
some 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

rhlEAtp-dependent rna helicase rhle; DEAD-box RNA helicase involved in ribosome assembly. Has RNA- dependent ATPase activity and unwinds double-stranded RNA. May play a role in the interconversion of ribosomal RNA-folding intermediates that are further processed by DeaD or SrmB during ribosome maturation (454 aa)    
Predicted Functional Partners:
cspA
Rna chaperone and antiterminator, cold-inducible; Binds to and stimulates the transcription of the CCAAT- containing, cold-shock-inducible promoters of the H-NS and GyrA proteins. Binds also to the inverted repeat 5'-ATTGG-3'
   
 0.779
pnp
Polynucleotide phosphorylase/polyadenylase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. Also involved, along with RNase II, in tRNA processing. RNases II and R contribute to rRNA degradation during starvation, while RNase R and PNPase are the major contributors to quality control of rRNA during steady state growth

hrpA
Atp-dependent rna helicase hrpa; Not yet known
   
 0.756
rraA
Ribonuclease e (rnase e) inhibitor protein; Globally modulates RNA abundance by binding to RNase E (Rne) and regulating its endonucleolytic activity. Can modulate Rne action in a substrate-dependent manner by altering the composition of the degradosome. Modulates RNA-binding and helicase activities of the degradosome
      
 0.712
rnc
Ribonuclease iii; Digests double-stranded RNA formed within single-strand substrates, but not RNA-DNA hybrids. Involved in the processing of rRNA precursors, viral transcripts, some mRNAs and at least 1 tRNA (metY, a minor form of tRNA-init-Met). Cleaves the 30S primary rRNA transcript to yield the immediate precursors to the 16S and 23S rRNAs; cleavage can occur in assembled 30S, 50S and even 70S subunits and is influenced by the presence of ribosomal proteins. The E.coli enzyme does not cleave R.capsulatus rRNA precursor, although R.capsulatus will complement an E.coli disruption, sh [...]

rne
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. Can also process other RNA species, such as RNAI, a molecule that controls the replication of ColE1 plasmid, and the cell division inhibitor DicF- RNA. It initiates the decay of RNAs by cutting them internally near their 5'-end. It is able to remove poly(A) tails by an endonucleolytic process. Required to initiate rRNA degradation during both starvation and quality control; acts after RNase PH [...]
   
 
 0.667
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. RNA-dependent NTPase which utilizes all four ribonucleoside triphosphates as substrates
     
 0.651
ybiH
Tetr/acrr family transcriptional regulator, regulator of cefoperazone and chloramphenicol sensitivity; Regulates transcription of the cecR-ybhGFSR operon and the rhlE gene, which altogether are involved in the control of sensitivity to cefoperazone and chloramphenicol. Represses the cecR-ybhGFSR operon and activates the rhlE operon. Acts by binding to a palindromic sequence within the intergenic spacer located between these two divergently transcribed operons
     
 0.618
ybhG
Putative membrane fusion protein (mfp) component of efflux pump, membrane anchor; Could be involved in the sensitivity control to chloramphenicol
     
 0.595
hfq
Rna-binding protein hfq; 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. Involved in the regulation of stress responses mediated by the sigma factors RpoS, sigma-E and sigma-32 . Binds with high specificity to tRNAs . Binds sRNA antitoxin RalA . In vitro, stimulates synthesis of long tails by poly(A) polymerase I . Required for RNA phage Qbeta replication . Seems to play a role in persister cell formation; upon overexpression decreas [...]
