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

yqiCBMFP family putative fusogenic protein; Required for efficient ubiquinone (coenzyme Q) biosynthesis under aerobic conditions. UbiK is probably an accessory factor of Ubi enzymes and facilitates ubiquinone biosynthesis by acting as an assembly factor, a targeting factor, or both. Dispensable for ubiquinone biosynthesis under anaerobiosis. (96 aa)    
Predicted Functional Partners:
ubiJ
Aerobic ubiquinone synthesis protein, SCP2 family protein; Required for ubiquinone (coenzyme Q) biosynthesis under aerobic conditions. Binds hydrophobic ubiquinone biosynthetic intermediates via its SCP2 domain and is essential for the stability of the Ubi complex. May constitute a docking platform where Ubi enzymes assemble and access their SCP2-bound polyprenyl substrates.
  
 
 0.997
ubiI
2-octaprenylphenol hydroxylase, FAD-dependent; FAD-dependent monooxygenase required for the aerobic hydroxylation of 2-octaprenylphenol to 2-octaprenyl-6-hydroxy-phenol, the first hydroxylation step in coenzyme Q (ubiquinone) biosynthesis.
  
  
 0.991
ubiF
2-octaprenyl-3-methyl-6-methoxy-1,4-benzoquinol oxygenase; Catalyzes the hydroxylation of 2-octaprenyl-3-methyl-6- methoxy-1,4-benzoquinol during ubiquinone biosynthesis.
  
  
 0.988
ubiH
2-octaprenyl-6-methoxyphenol hydroxylase, FAD/NAD(P)-binding; Is likely an 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-benzoquinol.
  
  
 0.985
ubiG
Bifunctional 3-demethylubiquinone-9 3-methyltransferase/ 2-octaprenyl-6-hydroxy phenol methylase; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway.
   
 
 0.982
ubiE
Ubiquinone/menaquinone biosynthesis C-methyltransferase UbiE; 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).

smg
DUF494 family putative periplasmic protein; Belongs to the Smg family.
  
    0.688
yafS
Putative S-adenosyl-L-methionine-dependent methyltransferase.
  
     0.685
ftsQ
Divisome assembly protein, membrane anchored protein involved in growth of wall at septum; Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic. May control correct divisome assembly. Belongs to the FtsQ/DivIB family. FtsQ subfamily.
  
     0.658
ubiD
3-octaprenyl-4-hydroxybenzoate decarboxylase; Catalyzes the decarboxylation of 3-octaprenyl-4-hydroxy benzoate to 2-octaprenylphenol, an intermediate step in ubiquinone biosynthesis; Belongs to the UbiD family.
