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

trpEAnthranilate synthase; 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 concentrations of ammonia. (490 aa)    
Predicted Functional Partners:
trpC
Indole-3-glycerol phosphate synthase (IGPS). catalytic activity:1-(2-carboxyphenylamino)-1-deoxy-d-ribulose 5-phosphate = 1-(indol-3-yl)glycerol 3-phosphate + co(2) + h(2)o. pathway: tryptophan biosynthesis; fourth step. InterPro: Indole-3-glycerol phosphate synthase; High confidence in function and specificity; Belongs to the TrpC family.

trpD
1,4-alpha-glucan branching enzyme; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).
 
 0.999
trpG
Anthranilate synthase component II (Glutamine amido-transferase). catalytic activity: chorismate + l-glutamine = anthranilate + pyruvate + l-glutamate. pathway: tryptophan biosynthesis; first step. TIGRFAM: trpG_papA: glutamine amidotransferase of anthranilate synthase or para-aminobenzoate synthase; High confidence in function and specificity.
 0.999
trpF
N-(5-phosphoribosyl)anthranilate isomerase (PRAI) catalyzes the third step of tryptophan biosynthesis. Similar to sprot|TRPF_RALSO (56%) and to sprot|TRPF_PSEAE (58%). Pfam (PF00697): N-(5'phosphoribosyl)anthranilate isomerase (PRAI); High confidence in function and specificity.
 
 
 0.981
aroC
AroC protein; 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.

The glycosyl transferase family includes anthranilate phosphoribosyltransferase (TrpD, EC: 2.4.2.18) and thymidine phosphorylase (EC: 2.4.2.2). All these proteins can transfer a phosphorylated ribose substrate. Similar to sprot|YBIB_ECOLI (40%) and to sprot|TRPD_SULSO (25%). Pfam (PF02885): Glycosyl transferase, family 3; Family membership.
