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

ubiBHypothetical protein; Is probably a protein kinase regulator of UbiI activity which is involved in aerobic coenzyme Q (ubiquinone) biosynthesis. (546 aa)    
Predicted Functional Partners:
ubiE
Hypothetical protein; 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).

CKO_00177
COG: COG3165 Uncharacterized protein conserved in bacteria; Psort location: Cytoplasmic, score:8.96.
  
  
 0.845
tatB
Hypothetical protein; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatC, TatB is part of a receptor directly interacting with Tat signal peptides. TatB may form an oligomeric binding site that transiently accommodates folded Tat precursor proteins before their translocation.
  
  
 0.709
tatC
Hypothetical protein; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatB, TatC is part of a receptor directly interacting with Tat signal peptides.

CKO_04271
Hypothetical protein; KEGG: ssn:SSO_3059 2.1e-193 visC; hypothetical protein; COG: COG0654 2-polyprenyl-6-methoxyphenol hydroxylase and related FAD-dependent oxidoreductases; Psort location: Cytoplasmic, score:8.96.
  
 
 0.690
ubiG
Hypothetical protein; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway; Belongs to the methyltransferase superfamily. UbiG/COQ3 family.
  
 
 0.687
tatA
Hypothetical protein; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. TatA could form the protein-conducting channel of the Tat system.
  
  
 0.671
znuC
Hypothetical protein; Part of the ABC transporter complex ZnuABC involved in zinc import. Responsible for energy coupling to the transport system. Belongs to the ABC transporter superfamily. Zinc importer (TC 3.A.1.15.5) family.
      0.626
ubiA
Hypothetical protein; 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.
