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

yqiCPutative cytoplasmic 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. Required for proliferation in macrophages and virulence in mice. Significantly contributes to colonization and invasion as well as host inflammation and innate immunity after infection. In vitro, has membrane fusogenic activity at acidic pH. (119 aa)    
Predicted Functional Partners:
yqiE
Putative resistance protein; Similar to E. coli orf, hypothetical protein (AAC76070.1); Blastp hit to AAC76070.1 (209 aa), 87% identity in aa 1 - 208.
      
 0.832
yigP
Putative inner membrane 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 (By similarity). May constitute a docking platform where Ubi enzymes assemble and access their SCP2-bound polyprenyl substrates (By similarity). Required for intracellular proliferation in macrophages. Belongs to the UbiJ family.

ybjT
Putative nucleoside-diphosphate-sugar epimerase; Similar to E. coli putative dTDP-glucose enzyme (AAC73956.1); Blastp hit to AAC73956.1 (486 aa), 84% identity in aa 11 - 486.
      
 0.790
ychK
Putative phosphoesterase; Similar to E. coli orf, hypothetical protein (AAC74316.1); Blastp hit to AAC74316.1 (314 aa), 83% identity in aa 14 - 314.
      
 0.765
yafS
Putative SAM-dependent methyltransferase; Similar to E. coli orf, hypothetical protein (AAC73318.1); Blastp hit to AAC73318.1 (246 aa), 86% identity in aa 7 - 244.
  
     0.699
yaiV
Putative inner membrane protein; Involved in oxidative stress resistance.
      
 0.697
smg
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC76309.1); Blastp hit to AAC76309.1 (157 aa), 94% identity in aa 1 - 157; Belongs to the Smg family.
  
    0.645
cca
tRNA nucleotidyl transferase; Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate. Also shows phosphatase, 2'-nucleotidase and 2',3'-cyclic phosphodiesterase activities. These phosphohydrolase activities are probably involved in the repair of the tRNA 3'-CCA terminus degraded by intracellular RNases.
  
     0.613
rseB
Anti sigma E (sigma 24) factor, negative regulator; Similar to E. coli regulates activity of sigma-E factor (AAC75624.1); Blastp hit to AAC75624.1 (318 aa), 89% identity in aa 1 - 318.
  
     0.611
ftsQ
Cell division protein; 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.
