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

ubiA4-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. (287 aa)    
Predicted Functional Partners:
ubiC
Putative chorismate:pyruvate lyase; Removes the pyruvyl group from chorismate, with concomitant aromatization of the ring, to provide 4-hydroxybenzoate (4HB) for the ubiquinone pathway; Belongs to the UbiC family.
    
 0.990
yigC
3-polyprenyl-4-hydroxybenzoate decarboxylase and related dec; Catalyzes the decarboxylation of 3-octaprenyl-4-hydroxy benzoate to 2-octaprenylphenol, an intermediate step in ubiquinone biosynthesis.
 
  
 0.987
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; Belongs to the UbiX/PAD1 family.

ispB
Octaprenyl-diphosphate synthase; Polyprenyl synthetase,82% identity to TrEMBL;Q5P1Y1. Has Pfam;PF00348, Polyprenyl synthetase.(IPR000092,Polyprenyl_synt)A variety of isoprenoid compounds are synthesized by various organisms. For example in eukaryotes the isoprenoid biosynthetic pathway is responsible for the synthesis of a variety of end products including cholesterol, dolichol, ubiquinone or coenzyme Q. In bacteria this pathway leads to the synthesis of isopentenyl tRNA, isoprenoid quinones, and sugar carrier lipids. Among the enzymes that participate in that pathway, are a number of [...]

ubiG
3-demethylubiquinone-9 3-O-methyltransferase; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway; Belongs to the methyltransferase superfamily. UbiG/COQ3 family.
 
 0.808
atpD
ATP synthase beta chain; Produces ATP from ADP in the presence of a proton gradient across the membrane. The catalytic sites are hosted primarily by the beta subunits; Belongs to the ATPase alpha/beta chains family.

azo0723
Putative monoxygenase. Pfam: Monoxygenase InterPro: Aromatic-ring hydroxylase (flavoprotein monoxygenase); High confidence in function and specificity.
  
   
 0.706
azo0476
Conserved hypothetical endoribonuclase L-PSP. Homology to orf1 of A. vineladii of 74% (sprot|YVN1_AZOVI(SRS)) This protein was described initially as an inhibitor of protein synthesis intiation but is now viewed as an endoribonuclease active on single-stranded mRNA. The cleavage of mRNA is responsible for the inhibition of protein synthesis. A role in purine regulation has also been suggested. Tigrfam: Endoribonuclease L-PSP, putative Pfam: Endoribonuclease L-PSP (=YipgF family) no TMHs weak indication for signal peptide; Conserved hypothetical protein.

ubiH
Probable 2-octaprenyl-6-methoxyphenol hydroxylase oxidoreductase protein; ubiH; aromatic-ring hydroxylase (flavoprotein monooxygenase) Oxygenase that introduces the hydroxyl group at carbon four of 2-octaprenyl-6-methoxyphenol resulting in the formation of 2-octaprenyl-6-methoxy-1,4-benzoquinone. Ubiquinone biosynthesis pathway, by similarity; High confidence in function and specificity.
