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

frlRPutative DNA-binding transcriptional regulator; May regulate the transcription of the frlABCDR operon, involved in the utilization of fructoselysine and psicoselysine. (243 aa)    
Predicted Functional Partners:
frlD
Fructoselysine 6-kinase; Catalyzes the ATP-dependent phosphorylation of fructoselysine to fructoselysine 6-phosphate. Functions in a fructoselysine degradation pathway that allows E.coli to grow on fructoselysine or psicoselysine. To a much lesser extenst, is also able to phosphorylate psicoselysine.
 
   
 0.954
frlC
Fructoselysine 3-epimerase; Catalyzes the reversible interconversion of fructoselysine with its C-3 epimer, psicoselysine. Allows E.coli to utilize psicoselysine for growth. Does not act on psicose or fructoselysine 6- phosphate.
 
   
 0.935
frlB
fructoselysine-6-P-deglycase; Catalyzes the reversible conversion of fructoselysine 6- phosphate to glucose 6-phosphate and lysine. Functions in a fructoselysine degradation pathway that allows E.coli to grow on fructoselysine or psicoselysine.
 
  
 0.922
psuK
Pseudouridine kinase; Catalyzes the phosphorylation of pseudouridine to pseudouridine 5'-phosphate (PsiMP).
     
 0.812
frlA
Putative fructoselysine transporter; Is likely involved in the transport of fructoselysine and psicoselysine to the cytoplasm, where they are degraded.
 
   
 0.790
nadR
Trifunctional NAD biosynthesis/regulator protein NadR; This enzyme has three activities: DNA binding, nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The DNA-binding domain binds to the nadB operator sequence in an NAD- and ATP-dependent manner. As NAD levels increase within the cell, the affinity of NadR for the nadB operator regions of nadA, nadB, and pncB increases, repressing the transcription of these genes. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity [...]
   
  
 0.787
tdcR
L-threonine dehydratase operon activator protein; Probable trans-acting positive activator for the tdc operon.
      
 0.733
ydiP
Putative ARAC-type regulatory protein; Protein involved in transcription and regulation of transcription, DNA-dependent.
  
  
 0.690
dgoR
D-galactonate catabolism operon transcriptional repressor; Repressor for the dgoRKAT operon. Binds D-galactonate as an inducer.
  
  
 0.683
srlR
Sorbitol-inducible srl operon transcriptional repressor; Regulator for gut (srl), glucitol operon; Protein involved in carbohydrate catabolic process, transcription and regulation of transcription, DNA-dependent.
      
 0.620
