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

cspERNA 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. (69 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.
   
 
 0.860
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).

yobF
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC74894.1); Blastp hit to AAC74894.1 (47 aa), 93% identity in aa 1 - 47.
   
  
 0.793
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.
  
 
 0.755
acpP
Acyl carrier protein; Carrier of the growing fatty acid chain in fatty acid biosynthesis; Belongs to the acyl carrier protein (ACP) family.
   
 
 0.751
rnb
RNase II; Involved in mRNA degradation. Hydrolyzes single-stranded polyribonucleotides processively in the 3' to 5' direction.
      
 0.700
ptsH
Phosphohistidinoprotein-hexose phosphotransferase; General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the PTS EIIA domain.
   
    0.686
rpsO
30S ribosomal subunit protein S15; 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.
   
 
 0.656
proQ
Activator 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.
   
  
 0.636
rpmJ
Similar to E. coli 50S ribosomal subunit protein L36 (AAC76324.1); Blastp hit to AAC76324.1 (38 aa), 100% identity in aa 1 - 38; Belongs to the bacterial ribosomal protein bL36 family.
