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

trpEThe anthranilate synthase catalyzes the formation of anthranilate from chorismate and L-glutamine, the first step in the biosynthesis of tryptophan. The enzyme is a Tetramer of two components I and two components II. The component I only catalyzes the formation of anthranilate using chorismate and ammonia rather than glutamine; The anthranilate synthase is regulated by feedback inhibition by tryptophan; Belongs to the anthranilate synthase component I family; Localized in the cytoplasm; High confidence in function and specificity.

Predicted Functional Partners:
trpG
Anthranilate synthase component II (glutamine amidotransferase); The anthranilate synthase catalyzes the formation of anthranilate from chorismate and L-glutamine, the first step in the biosynthesis of tryptophan. The enzyme is a Tetramer of two components I and two components II. Associated with the component I, the component II of the anthranilate synthase provides the glutamine amidotransferase activity (GATase, 2.4.2.-) that catalyses the removal of the ammonia group from a glutamate molecule and its subsequent transfer to a specific substrate, thus creating a new carbon-nitrogen g [...]

trpD
Anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).
 0.999
trpC
Indole-3-glycerol phosphate synthase (IGPS) catalyzes the ring closure of 1-(2-carboxy-phenylamino)-1-deoxyribulose into indol-3-glycerol-phosphate, the fourth step in the biosynthesis of tryptophan; Localized in the cytoplasm; High confidence in function and specificity; Belongs to the TrpC family.
 
 0.998
trpF
The N-(5'-phosphoribosyl)anthranilate isomerase (PRAI) converts the N-(5-phospho-beta-D-ribosyl)anthranilate to 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate, the third step in the biosynthesis of tryptophan; Localized in the cytoplasm; High confidence in function and specificity; Belongs to the TrpF family.

aroC
Chorismate synthase; 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.

trpB1
Tryptophan synthase beta subunit; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
 
  
 0.957
trpA
Tryptophan synthase, alpha subunit; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.
 
  
 0.955
menF
The isochorismate synthase, called also isochorismate mutase catalyses the conversion of chorismate to isochorismate, the first step in the biosynthesis of both respiratory chain components: menaquinone (MK, vitamin K2) and phylloquinone (vitamin K1); Localized in the cytoplasm; High confidence in function and specificity.
  
  
 0.947
aroGH
Bifunctional enzyme including 3-deoxy-7-phosphoheptulonate synthase (DAHP synthase) in N-terminus and chorismate mutase in C-terminus. DAHP synthase catalyzes the first step in the common pathway leading to the biosynthesis of aromatic compounds, the stereospecific condensation of phosphoenolpyruvate and D-erythrose-4-phosphate giving rise to 3-deoxy-D-arabino-heptulosonate-7-phosphate (DAHP). Chorismate mutase catalyzes the conversion of chorismate to prephenate in the pathway of tyrosine and phenylalanine biosynthesis. Localized in the cytoplasm; High confidence in function and speci [...]
