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

nemRTranscriptional repressor for the nemRA-gloA operon, quinone-, glyoxal-, and HOCl-activated; Involved in response to both electrophiles and reactive chlorine species (RCS). Represses the transcription of the nemRA-gloA operon by binding to the NemR box. May sense electrophiles, primarily quinones and glyoxals, as redox signals and regulate the redox state by modulating the expression of nemA and gloA. Also uses the oxidation status of HOCl-sensitive cysteine residues to respond to bleach and related RCS. Involved in response to methylglyoxal. (199 aa)    
Predicted Functional Partners:
nemA
Chromate reductase, quinone reductase, FMN-linked; Involved in the degradation of toxic compounds. Can use a variety of substrates, including the nitrate ester explosives glycerol trinitrate (GTN) and pentaerythritol tetranitrate (PETN), chromate and various electrophiles such as quinones. Involved in resistance to hypochlorous acid (HOCl), which is the active component of household bleach and a powerful antimicrobial during the innate immune response. Catalyzes the reduction of N- ethylmaleimide (NEM) to N-ethylsuccinimide. Together with NfsA and NfsB, can use the nitroaromatic explos [...]

gloA
Glyoxalase I, Ni-dependent; Catalyzes the isomerization of the hemithioacetal formed spontaneously from methylglyoxal and glutathione, to S- lactoylglutathione, which is then hydrolyzed by a type II glyoxalase (GloB or GloC). Is involved in methylglyoxal (MG) detoxification (Probable). Involved in resistance to hypochlorous acid (HOCl), which is the active component of household bleach and a powerful antimicrobial during the innate immune response.
  
  
 0.942
hypT
Hypochlorite-responsive transcription factor; Protects cells from HOCl (hypochlorite) stress but not peroxide or diamide stress. Decreases the intracellular load of reactive oxygen species by up-regulating genes involved in methionine and cysteine biosynthesis and down-regulating Fur-regulated genes involved in iron acquisition. Has also been suggested to down-regulate expression of the flagellar regulon, decreasing motility, but this activity was not confirmed in a second study. Belongs to the LysR transcriptional regulatory family.
   
  
 0.901
rclR
Reactive chlorine species (RCS)-specific activator of the rcl genes; Involved in reactive chlorine species (RCS) stress resistance. Upregulates, in response to hypochlorous acid (HOCl), the expression of three genes essential for survival of RCS stress (rclA, rclB and rclC) and its own expression.
      
 0.893
rcdA
Transcriptional regulator of csgD and ybiJI; Regulates the expression of a number of genes involved in biofilm formation and stress response. Target genes include six stress- response transcriptional regulators: csgD, which is a master regulator of biofilm formation, appY, sxy, ycgF, fimB and rcdA itself. This indicates that a large number of genes must be regulated indirectly via these transcriptional regulators. Acts by binding to the upstream region of its target genes.
  
  
 0.690
rutR
Rut operon transcriptional repressor for; Master transcription regulator which represses the degradation of pyrimidines (rutABCDEFG) and purines (gcl operon) for maintenance of metabolic balance between pyrimidines and purines. It also regulates the synthesis of pyrimidine nucleotides and arginine from glutamine (carAB) and the supply of glutamate (gadABWX).

ydhL
DUF1289 family protein.
  
  
 0.665
hslO
Heat shock protein Hsp33; Redox regulated molecular chaperone. Protects both thermally unfolding and oxidatively damaged proteins from irreversible aggregation. Plays an important role in the bacterial defense system toward oxidative stress.
      
 0.645
ttdR
Transcriptional activator of ttdABT; Positive regulator required for L-tartrate-dependent anaerobic growth on glycerol. Induces expression of the ttdA-ttdB-ygjE operon.
      
 0.643
yqhC
Transcriptional activator of yqhD; Putative ARAC-type regulatory protein; Protein involved in transcription activator activity and transcription.
