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

Predicted Functional Partners:
ubiG
Ubiquinone biosynthesis O-methyltransferase; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway; Belongs to the methyltransferase superfamily. UbiG/COQ3 family.
  
   
 0.678
smpB
SsrA-binding protein; Required for rescue of stalled ribosomes mediated by trans- translation. Binds to transfer-messenger RNA (tmRNA), required for stable association of tmRNA with ribosomes. tmRNA and SmpB together mimic tRNA shape, replacing the anticodon stem-loop with SmpB. tmRNA is encoded by the ssrA gene; the 2 termini fold to resemble tRNA(Ala) and it encodes a 'tag peptide', a short internal open reading frame. During trans-translation Ala-aminoacylated tmRNA acts like a tRNA, entering the A-site of stalled ribosomes, displacing the stalled mRNA. The ribosome then switches to [...]

visC
Putative oxidoreductase involved in anerobic synthesis of ubiquinone, FAD/NAD(P)-binding domain; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
  
  
 0.638
dnaQ
DNA polymerase III subunit epsilon; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. The epsilon subunit contain the editing function and is a proofreading 3'- 5' exonuclease.
  
     0.627
ubiA
4-hydroxybenzoate octaprenyltransferase; Catalyzes the prenylation of para-hydroxybenzoate (PHB) with an all-trans polyprenyl group. Mediates the second step in the final reaction sequence of ubiquinone-8 (UQ-8) biosynthesis, which is the condensation of the polyisoprenoid side chain with PHB, generating the first membrane-bound Q intermediate 3-octaprenyl-4-hydroxybenzoate.
  
 
 0.577
PP_0058
Putative 1-acyl-sn-glycerol-3-phosphate acyltransferase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology.
 
     0.563
ubiH
2-octaprenyl-6-methoxyphenyl hydroxylase.
  
  
 0.511
hflD
HflD-like high frequency lysogenization protein; Function of homologous gene experimentally demonstrated in an other organism; regulator; Transport and binding proteins.
  
     0.507
bioC
Malonyl-[acyl-carrier protein] O-methyltransferase; Converts the free carboxyl group of a malonyl-thioester to its methyl ester by transfer of a methyl group from S-adenosyl-L- methionine (SAM). It allows to synthesize pimeloyl-ACP via the fatty acid synthetic pathway.
  
   
 0.483
sspA
Stringent starvation protein A; Function of homologous gene experimentally demonstrated in an other organism; regulator; Transcription.
  
     0.469
