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

trpCIndole-3-glycerol phosphate synthase; Belongs to the TrpC family. (257 aa)    
Predicted Functional Partners:
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.
 
 0.999
trpD1
Phosphoribosylanthranilate transferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).
  
 0.999
trpF
Phosphoribosyl anthranilate isomerase; Belongs to the TrpF family.
 
 0.999
trpG
Anthranilate synthase component II.
  
 0.999
trpE
Anthranilate synthase component I; 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 concentr [...]
 
 0.999
trpB1
Tryptophan synthase beta subunit; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
 
 0.999
pabB
P-aminobenzoate synthetase.
 
 0.995
trpD2
Phosphoribosylanthranilate transferase; Belongs to the anthranilate phosphoribosyltransferase family.
 
  
 0.973
trpB2
Tryptophan synthase beta subunit; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
 
 
 0.942
hisA
Phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase.
