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

ubiAP-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. (290 aa)    
Predicted Functional Partners:
ubiC
Chorismate pyruvate lyase; Removes the pyruvyl group from chorismate, with concomitant aromatization of the ring, to provide 4-hydroxybenzoate (4HB) for the ubiquinone pathway.
 
 
 0.998
yigC-2
Putative oxidoreductase; Catalyzes the decarboxylation of 3-octaprenyl-4-hydroxy benzoate to 2-octaprenylphenol, an intermediate step in ubiquinone biosynthesis.
 
 
 0.990
ubiG
3-demethylubiquinone-9 3-methyltransferase; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway; Belongs to the methyltransferase superfamily. UbiG/COQ3 family.
 
 
 0.976
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.
 
  
 0.970
ubiE
S-adenosylmethionine; 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).
 
   
 0.957
ubiF
Putative monooxygenase; Similar to E. coli orf, hypothetical protein (AAC73763.1); Blastp hit to AAC73763.1 (391 aa), 85% identity in aa 1 - 391.
  
   
 0.943
STM2921
Putative flavoprotein; Involved in the non-oxidative decarboxylation and detoxification of phenolic derivatives. Flavin prenyltransferase that catalyzes the synthesis of the prenylated FMN cofactor (prenyl-FMN) for phenolic acid decarboxylase.
 
  
 0.933
ubiH
2-octaprenyl-6-methoxyphynol hydroxylase; Similar to E. coli 2-octaprenyl-6-methoxyphenol--> 2-octaprenyl-6-methoxy-1, 4-benzoquinone (AAC75945.1); Blastp hit to AAC75945.1 (392 aa), 79% identity in aa 1 - 392.
  
   
 0.904
ispB
Similar to E. coli octaprenyl diphosphate synthase (AAC76219.1); Blastp hit to AAC76219.1 (323 aa), 95% identity in aa 1 - 323; Belongs to the FPP/GGPP synthase family.
 
 
 0.901
ydhD
Putative glutaredoxin protein; Similar to E. coli orf, hypothetical protein (AAC74726.1); Blastp hit to AAC74726.1 (115 aa), 97% identity in aa 1 - 115; Belongs to the glutaredoxin family. Monothiol subfamily.
