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

ttrRTetrathionate reductase complex: response regulator; Member of the two-component regulatory system TtrR/TtrS, which is required for synthesis of tetrathionate reductase. Positively regulates transcription of the ttrBCA operon. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut. (206 aa)    
Predicted Functional Partners:
ttrS
Tetrathionate reductase complex: sensory transduction histidine kinase; Member of the two-component regulatory system TtrR/TtrS, which is required for synthesis of tetrathionate reductase. Probably functions as a sensor protein kinase which is autophosphorylated at a histidine residue in response to tetrathionate, and transfers its phosphate group to TtrR. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut.
 0.999
ttrC
Tetrathionate reductase complex, subunit C; Part of a membrane-bound tetrathionate reductase that catalyzes the reduction of tetrathionate to thiosulfate. TtrC probably anchors TtrA and TtrB to the periplasmic face of the cytoplasmic membrane. May transfer electrons from membrane quinol to TtrB. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut. Belongs to the NrfD family.
 
  
 0.976
ttrB
Tetrathionate reductase complex, subunit B; Part of a membrane-bound tetrathionate reductase that catalyzes the reduction of tetrathionate to thiosulfate. TtrB is probably involved in transfer of electrons from TtrC to TtrA. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut.
 
   
 0.927
cheR
Glutamate methyltransferase; Methylation of the membrane-bound methyl-accepting chemotaxis proteins (MCP) to form gamma-glutamyl methyl ester residues in MCP.
    
 0.904
ttrA
Tetrathionate reductase complex, subunit A; Part of a membrane-bound tetrathionate reductase that catalyzes the reduction of tetrathionate to thiosulfate. TtrA is the catalytic subunit. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
 
  
 0.902
orf70
Putative cytoplasmic protein; In vitro catalyzes the addition of water to fumarate, forming malate. Cannot catalyze the reverse reaction. Cannot use the cis-isomer maleate as substrate; Belongs to the FumD family.
  
  
 0.751
arcB
Sensory histidine kinase in two-component regulatory system with ArcA; Senses redox conditions; similar to E. coli aerobic respiration sensor-response protein; histidine protein kinase/phosphatase, sensor for arcA (AAC76242.1); Blastp hit to AAC76242.1 (776 aa), 93% identity in aa 1 - 776.
  
 
 0.691
yegE
Putative PAS/PAC domain protein; Diguanylate cyclase/phosphodiesterase domain 1 and Diguanylate cyclase/phosphodiesterase domain 2 containing; similar to E. coli putative sensor-type protein (AAC75128.1); Blastp hit to AAC75128.1 (1105 aa), 76% identity in aa 540 - 437.

torS
Histidine kinase; Regulates tor operon; similar to E. coli sensor protein torS (regulator TorR) (AAC74078.1); Blastp hit to AAC74078.1 (904 aa), 62% identity in aa 1 - 896.
 
 
 0.621
barA
Sensory histidine kinase; Similar to E. coli sensor-regulator, activates OmpR by phophorylation (AAC75828.1); Blastp hit to AAC75828.1 (918 aa), 90% identity in aa 1 - 918.
