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

yigCPutative oxidoreductase; Catalyzes the decarboxylation of 3-octaprenyl-4-hydroxy benzoate to 2-octaprenylphenol, an intermediate step in ubiquinone biosynthesis. (497 aa)    
Predicted Functional Partners:
ubiX
3-octaprenyl-4-hydroxybenzoate carboxy-lyase; Flavin prenyltransferase that catalyzes the synthesis of the prenylated FMN cofactor (prenyl-FMN) for 4-hydroxy-3-polyprenylbenzoic acid decarboxylase UbiD. The prenyltransferase is metal-independent and links a dimethylallyl moiety from dimethylallyl monophosphate (DMAP) to the flavin N5 and C6 atoms of FMN.
 
 
 0.988
ecdB
Putative decarboxylase; Involved in the non-oxidative decarboxylation and detoxification of phenolic derivatives under both aerobic and anaerobic conditions. Flavin prenyltransferase that catalyzes the synthesis of the prenylated FMN cofactor (prenyl-FMN) for phenolic acid decarboxylase (By similarity); Belongs to the UbiX/PAD1 family. YclB subfamily.
 
 
 0.985
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.

visC
Orf, hypothetical protein; Residues 1 to 400 of 400 are 98.75 pct identical to residues 1 to 400 of 400 from Escherichia coli K-12 Strain MG1655: B2906.
     
 0.927
ubiE
2-octaprenyl-6-methoxy-1,4-benzoquinone --> 2-octaprenyl-3-methyl-6-methoxy-1,4-benzoquinone; Methyltransferase required for the conversion of demethylmenaquinol (DMKH2) to menaquinol (MKH2) and the conversion of 2-polyprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-polyprenyl-3- methyl-6-methoxy-1,4-benzoquinol (DMQH2).
 
  
 0.835
ubiB
Ferrisiderophore reductase; Catalyzes the reduction of soluble flavins by reduced pyridine nucleotides; Belongs to the Fre/LuxG FAD/NAD(P) flavoprotein oxidoreductase family.
  
    0.815
ubiG
3-demethylubiquinone-9 3-methyltransferase and 2-octaprenyl-6-hydroxy phenol methylase; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway; Belongs to the methyltransferase superfamily. UbiG/COQ3 family.
      
 0.611
yigP
Orf, hypothetical protein; Residues 1 to 201 of 201 are 98.50 pct identical to residues 1 to 201 of 201 from Escherichia coli K-12 Strain MG1655: B3834.
   
  
 0.593
rfaH
Transcription antitermination protein RfaH; Enhances distal genes transcription elongation in a specialized subset of operons that encode extracytoplasmic components. RfaH is recruited into a multi-component RNA polymerase complex by the ops element, which is a short conserved DNA sequence located downstream of the main promoter of these operons. Once bound, RfaH suppresses pausing and inhibits Rho-dependent and intrinsic termination at a subset of sites. Termination signals are bypassed, which allows complete synthesis of long RNA chains.
  
  
 0.530
yleB
Orf, hypothetical protein; Residues 1 to 391 of 391 are 98.20 pct identical to residues 1 to 391 of 391 from Escherichia coli K-12 Strain MG1655: B0662.
