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

aroCChorismate synthase (aroC); Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system. (378 aa)    
Predicted Functional Partners:
aroA-2
3-phosphoshikimate-1-carboxyvinyltransferase (aroA); Catalyzes the transfer of the enolpyruvyl moiety of phosphoenolpyruvate (PEP) to the 5-hydroxyl of shikimate-3-phosphate (S3P) to produce enolpyruvyl shikimate-3-phosphate and inorganic phosphate.
 
 0.999
aroQ
Chorismate mutase/prephenate dehydratase (pheA); Catalyzes the conversion of chorismate into prephenate via a Claisen rearrangement.
  
 
 0.991
aroE
Shikimate 5-dehydrogenase (aroE); Involved in the biosynthesis of the chorismate, which leads to the biosynthesis of aromatic amino acids. Catalyzes the reversible NADPH linked reduction of 3-dehydroshikimate (DHSA) to yield shikimate (SA).
  
 0.986
trpE
Anthranilate synthase component I (trpE); Part of a heterotetrameric complex that catalyzes the two- step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly from chorismate and high c [...]

aroD
3-dehydroquinate dehydratase (aroD); Involved in the third step of the chorismate pathway, which leads to the biosynthesis of aromatic amino acids. Catalyzes the cis- dehydration of 3-dehydroquinate (DHQ) and introduces the first double bond of the aromatic ring to yield 3-dehydroshikimate. Belongs to the type-I 3-dehydroquinase family.

aroK
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 44.16; identified by sequence similarity; putative.
     
 0.927
trpA
Tryptophan synthase alpha subunit (trpA); The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.
  
  
 0.913
hisC
Histidinol-phosphate aminotransferase (hisC); Similar to SP:P06986 GB:U02071 GB:X03416 PID:41695 PID:41710 percent identity: 29.00; identified by sequence similarity; putative.

aroB
Conserved hypothetical protein; Catalyzes the oxidative deamination and cyclization of 2- amino-3,7-dideoxy-D-threo-hept-6-ulosonic acid (ADH) to yield 3- dehydroquinate (DHQ), which is fed into the canonical shikimic pathway of aromatic amino acid biosynthesis; Belongs to the archaeal-type DHQ synthase family.
