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.

Score
cpxASensory 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. (457 aa)    
Predicted Functional Partners:
cpxR
Response reguator in two-component regulatory system with CpxA; Regulates expression of protein folding and degrading factors (OmpR family); similar to E. coli transcriptional regulator in 2-component system (AAC76894.1); Blastp hit to AAC76894.1 (232 aa), 97% identity in aa 1 - 232.
 0.999
baeR
OmpR family; similar to E. coli transcriptional response regulatory protein (sensor BaeS) (AAC75140.1); Blastp hit to AAC75140.1 (240 aa), 96% identity in aa 1 - 240.
 
 0.976
ompR
Response regulator in two-component regulatory system with EnvZ; 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). Plays a central role in both acid and osmotic stress responses. Binds to the promoter of both ompC and ompF; at low osmolarity it activates ompF transcription, while at high osmolarity it represses ompF and activates ompC transcription (By similarity).
 
 0.963
cpxP
Periplasmic repressor of cpx regulon by interaction with CpxA; Rescue from transitory stresses; similar to E. coli orf, hypothetical protein (AAC76896.1); Blastp hit to AAC76896.1 (122 aa), 94% identity in aa 1 - 122.
     
 0.963
phoP
Response regulator in two-component regulatory system with PhoQ; Member of the two-component regulatory system PhoP/PhoQ which regulates the expression of genes involved in virulence, adaptation to acidic and low Mg(2+) environments and resistance to host defense antimicrobial peptides. Essential for intramacrophage survival of S.typhimurium. In low periplasmic Mg(2+), PhoQ phosphorylates PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP-repressed genes (PRG). In high periplasmic Mg(2+), PhoQ dephosphorylates phospho-PhoP, resulting in the repressio [...]

rstA
Similar to E. coli response transcriptional regulatory protein (RstB sensor) (AAC74680.1); Blastp hit to AAC74680.1 (242 aa), 84% identity in aa 4 - 242.
 
 0.920
basR
Response regulator in two-component regulatory system with BasS; Member of the two-component regulatory system BasS/BasR. BasR induces the transcription of the ugd, ais, arnBCADTEF and eptA-basRS loci, all involved in resistance to polymyxin. Represses the transcription of pmrD. Plays a role in the adaptation of the organism to the host environment, in particular to neutrophils, and therefore it plays a role in virulence as well.

ompF
Outer membrane protein 1a (ia;b;f), porin; Forms pores that allow passive diffusion of small molecules across the outer membrane. It is also a receptor for the bacteriophage T2 (By similarity).
  
   
 0.905
ompC
Outer membrane protein 1b (ib;c); Forms pores that allow passive diffusion of small molecules across the outer membrane.
  
   
 0.900
htrA
Periplasmic serine protease Do, heat shock protein; DegP acts as a chaperone at low temperatures but switches to a peptidase (heat shock protein) at higher temperatures. It degrades transiently denatured and unfolded proteins which accumulate in the periplasm following heat shock or other stress conditions. DegP is efficient with Val-Xaa and Ile-Xaa peptide bonds, suggesting a preference for beta-branched side chain amino acids. Only unfolded proteins devoid of disulfide bonds appear capable of being cleaved, thereby preventing non-specific proteolysis of folded proteins. Its proteolyt [...]
