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

arcAResponse regulator (OmpR family) in two-component regulatory system with ArcB (or CpxA); Regulates genes in aerobic pathways; similar to E. coli negative response regulator of genes in aerobic pathways, (sensors, ArcB and CpxA) (AAC77354.1); Blastp hit to AAC77354.1 (238 aa), 99% identity in aa 1 - 238. (238 aa)    
Predicted Functional Partners:
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.
 0.999
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.
 
 
 0.858
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.
 
 
 0.823
STM0561
Sensor protein; Similar to E. coli putative 2-component sensor protein (AAC73671.1); Blastp hit to AAC73671.1 (480 aa), 74% identity in aa 375 - 479.
 
 
 0.816
envZ
Sensory histidine kinase in two-component regulatory system with OmpR; Member of the two-component regulatory system EnvZ/OmpR involved in osmoregulation (particularly of genes ompF and ompC) as well as other genes (By similarity). EnvZ functions as a membrane- associated protein kinase that phosphorylates OmpR in response to environmental signals; at low osmolarity OmpR activates ompF transcription, while at high osmolarity it represses ompF and activates ompC transcription (By similarity).
 
 0.808
cpxA
Sensory kinase in two-component regulatory system with CpxR; Senses misfolded proteins in bacterial envelope; similar to E. coli probable sensor protein (histidine protein kinase), acting on arcA (AAC76893.1); Blastp hit to AAC76893.1 (457 aa), 96% identity in aa 1 - 457.
 
 0.808
ssrA
Secretion system regulator: Sensor component; SpiR (gi|1498305).
 
 
 0.762
nuoC
NADH dehydrogenase I chain C,D; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; In the N-terminal section; belongs to the complex I 30 kDa subunit family.
  
   0.733
phoR
Sensory kinase in two-component regulatory system with PhoB, regulates pho regulon; Similar to E. coli positive and negative sensor protein for pho regulon (AAC73503.1); Blastp hit to AAC73503.1 (431 aa), 90% identity in aa 1 - 431.
 
 0.724
copS
Copper resistance; Member of a two-component regulatory system.
