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

trpBTryptophan synthase, beta chain; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine. (394 aa)    
Predicted Functional Partners:
trpA
Tryptophan synthase, alpha chain; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.

trpF
N-(5'phosphoribosyl)anthranilate isomerase; Citation: Sterner R, Kleemann GR, Szadkowski H, Lustig A, Hennig M, Kirschner K. (1996). Protein Sci. 5:2000-8; Belongs to the TrpF family.

trpG
Anthranilate synthase component II; Citation: Knochel T, Ivens A, Hester G, Gonzalez A, Bauerle R, Wilmanns M, Kirschner K, Jansonius JN.(1999). Proc Natl Acad Sci. 96:9479-.

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 [...]

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; Citation: Knochel T, Pappenberger A, Jansonius JN, Kirschner K. (2002). J Biol Chem. 277:8626-34.
 
 0.999
serB
Phosphoserine phosphatase; Citation: Wang W, Kim R, Jancarik J, Yokota H, Kim SH. (2001) Structure (Camb) 9:65-71.
  
 
 0.932
pssA
Archaetidylserine synthase; Citation: J Bacteriol. 2003 Feb;185(4):1181-9; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
    
 0.907
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.

hisI
Phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
