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:
some 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

aroF3-deoxy-D-arabino-heptulosonate-7-phosphate synthase, tyrosine-repressible; Stereospecific condensation of phosphoenolpyruvate (PEP) and D-erythrose-4-phosphate (E4P) giving rise to 3-deoxy-D-arabino- heptulosonate-7-phosphate (DAHP) (356 aa)    
Predicted Functional Partners:
tyrA
T-protein; Chorismate mutase-T and prephenate dehydrogenase; Protein involved in L-phenylalanine biosynthetic process and tyrosine biosynthetic process
 
 
 0.999
aroB
3-dehydroquinate synthase; Catalyzes the conversion of 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) to dehydroquinate (DHQ)
  
 
 0.990
pheA
Fused chorismate mutase/prephenate dehydratase; Catalyzes the Claisen rearrangement of chorismate to prephenate and the decarboxylation/dehydration of prephenate to phenylpyruvate
   
 
 0.959
aroL
Shikimate kinase ii; Catalyzes the specific phosphorylation of the 3-hydroxyl group of shikimic acid using ATP as a cosubstrate
  
  
 0.917
tyrR
Involved in transcriptional regulation of aromatic amino acid biosynthesis and transport. Modulates the expression of at least 8 unlinked operons. Seven of these operons are regulated in response to changes in the concentration of the three aromatic amino acids (phenylalanine, tyrosine and tryptophan). These amino acids are suggested to act as co-effectors which bind to the TyrR protein to form an active regulatory protein. In most cases TyrR causes negative regulation, but positive effects on the tyrP gene have been observed at high phenylalanine concentrations
      
 0.906
tktA
Transketolase 1, thiamine triphosphate-binding; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate. Thus, catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose- 5-phosphate
   
  
 0.882
tyrB
Tyrosine aminotransferase, tyrosine-repressible, plp-dependent; Broad-specificity enzyme that catalyzes the transamination of 2-ketoisocaproate, p-hydroxyphenylpyruvate, and phenylpyruvate to yield leucine, tyrosine, and phenylalanine, respectively. In vitro, is able to catalyze the conversion of beta-methyl phenylpyruvate to the nonproteinogenic amino acid (2S,3S)-beta-methyl-phenylalanine, a building block of the antibiotic mannopeptimycin produced by Streptomyces hygroscopicus NRRL3085
      
 0.876
aroK
Shikimate kinase 1; Catalyzes the specific phosphorylation of the 3-hydroxyl group of shikimic acid using ATP as a cosubstrate
     
 0.850
aroD
3-dehydroquinate dehydratase I; Involved in the third step of the chorismate pathway, which leads to the biosynthesis of aromatic amino acids (AroAA). Catalyzes the cis-dehydration of 3-dehydroquinate (DHQ) and introduces the first double bond of the aromatic ring to yield 3-dehydroshikimate. The reaction involves the formation of an imine intermediate between the keto group of 3-dehydroquinate and the epsylon-amino group of a lys-170 at the active site
     
 0.827
aroH
3-deoxy-D-arabino-heptulosonate-7-phosphate synthase, tryptophan repressible; Stereospecific condensation of phosphoenolpyruvate (PEP) and D-erythrose-4-phosphate (E4P) giving rise to 3-deoxy-D-arabino- heptulosonate-7-phosphate (DAHP)
