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

rbfARibosome-binding factor A; One of several proteins that assist in the late maturation steps of the functional core of the 30S ribosomal subunit. Associates with free 30S ribosomal subunits (but not with 30S subunits that are part of 70S ribosomes or polysomes). Required for efficient processing of 16S rRNA. May interact with the 5'-terminal helix region of 16S rRNA. (117 aa)    
Predicted Functional Partners:
infB
Initiation factor 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.
 
  
 0.998
truB
tRNA pseudouridine 55 synthase; Responsible for synthesis of pseudouridine from uracil-55 in the psi GC loop of transfer RNAs; Belongs to the pseudouridine synthase TruB family. Type 1 subfamily.
 
  
 0.989
ylxP
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
  
 0.960
rimP
Ribosome maturation factor; Required for maturation of 30S ribosomal subunits. Belongs to the RimP family.
  
 
 0.946
rpsO
Ribosomal protein S15 (BS18); 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.
  
 
 0.940
rimM
16S rRNA processing protein; An accessory protein needed during the final step in the assembly of 30S ribosomal subunit, possibly for assembly of the head region. Probably interacts with S19. Essential for efficient processing of 16S rRNA. May be needed both before and after RbfA during the maturation of 16S rRNA. It has affinity for free ribosomal 30S subunits but not for 70S ribosomes; Belongs to the RimM family.
 
  
 0.927
rpsQ
Ribosomal protein S17 (BS16); One of the primary rRNA binding proteins, it binds specifically to the 5'-end of 16S ribosomal RNA.
   
 
 0.893
rpsE
Ribosomal protein S5; With S4 and S12 plays an important role in translational accuracy; many suppressors of streptomycin-dependent mutants of protein S12 are found in this protein, some but not all of which decrease translational accuracy (ram, ribosomal ambiguity mutations); Belongs to the universal ribosomal protein uS5 family.
   
 
 0.883
rpsD
Ribosomal protein S4 (BS4); One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit. S4 represses its own expression; it is not know if this is at the level of translation or of mRNA stability; Belongs to the universal ribosomal protein uS4 family.

nrnA
Oligoribonuclease (nanoRNAse), 3',5'-bisphosphate nucleotidase; Bifunctional enzyme which has both oligoribonuclease and pAp- phosphatase activities. Degrades RNA and DNA oligonucleotides with a length of 5 nucleotides and shorter, with a preference for 3-mers. Directionality is controversial; shown to degrade 5-mers and less in a 3' to 5' direction , and 11-mers in a 5' to 3' direction. Converts 3'(2')-phosphoadenosine 5'- phosphate (PAP) to AMP.
