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

perRCP4-6 prophage; Apparent regulatory gene involved in peroxide resistance in stationary phase; Belongs to the LysR transcriptional regulatory family. (297 aa)    
Predicted Functional Partners:
oxyR
Oxidative and nitrosative stress transcriptional regulator; Hydrogen peroxide sensor. Activates the expression of a regulon of hydrogen peroxide-inducible genes such as katG, gor, ahpC, ahpF, oxyS (a regulatory RNA), dps, fur and grxA. OxyR expression is negatively autoregulated by binding to a 43 bp region upstream of its own coding sequence. OxyR is inactivated by reduction of its essential disulfide bond by the product of GrxA, itself positively regulated by OxyR. Has also a positive regulatory effect on the production of surface proteins that control the colony morphology and auto- [...]

mntR
Mn(2+)-responsive manganese regulon transcriptional regulator; In the presence of manganese, represses expression of mntH and mntS. Up-regulates expression of mntP.
    
 
 0.841
soxR
Redox-sensitive transcriptional activator of soxS; Activates the transcription of the soxS gene which itself controls the superoxide response regulon. SoxR contains a 2Fe-2S iron- sulfur cluster that may act as a redox sensor system that recognizes superoxide. The variable redox state of the Fe-S cluster is employed in vivo to modulate the transcriptional activity of SoxR in response to specific types of oxidative stress. Upon reduction of 2Fe-2S cluster, SoxR reversibly loses its transcriptional activity, but retains its DNA binding affinity.

ykfA
CP4-6 prophage; Putative GTP-binding protein; To E.coli YfjP and YeeP.
  
    0.797
ahpC
Alkyl hydroperoxide reductase, C22 subunit; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. Is the primary scavenger for endogenously generated hydrogen peroxides; Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
     
 0.704
frvA
Putative enzyme IIA component of PTS; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II FrvAB PTS system is involved in fructose transport.
      
 0.704
hcaR
Hca operon transcriptional regulator; Transcriptional activator of the hca operon for 3- phenylpropionic acid catabolism.
  
     0.702
katG
Catalase-peroxidase HPI, heme b-containing; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity. Displays also NADH oxidase, INH lyase and isonicotinoyl-NAD synthase activity; Belongs to the peroxidase family. Peroxidase/catalase subfamily.
     
 0.688
yiaU
Putative transcriptional regulator LYSR-type; Protein involved in transcription activator activity, transcription repressor activity and transcription; Belongs to the LysR transcriptional regulatory family.
  
   
 0.674
ynfL
Putative transcriptional regulator LYSR-type; Protein involved in regulation of transcription, DNA-dependent; Belongs to the LysR transcriptional regulatory family.
