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

trpB1Tryptophan synthase, subunit beta; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine. (388 aa)    
Predicted Functional Partners:
trpA
Tryptophan synthetase 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
trpF
Phosphoribosyl anthranilate isomerase; Function Code: 1.2 Amino Acid Biosynthesis: Aromatic amino acid family; (trpF); Belongs to the TrpF family.
 
  
 0.999
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
Indoleglycerol phosphate synthase; Function Code: 1.2 Amino Acid Biosynthesis: Aromatic amino acid family; (trpC); Belongs to the TrpC family.
 
 0.999
PF1708
Anthranilate synthase component II; Function Code: 1.2 Amino Acid Biosynthesis: Aromatic amino acid family; (trpG).
  
  
 0.998
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 [...]
 
  
 0.998
trpB2
Tryptophan synthase, subunit beta homolog; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
 
 
0.945
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with a modified folate serving as the one-carbon carrier. Also exhibits a pteridine-independent aldolase activity toward beta- hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
     
 0.945
PF1921
Phosphoserine phosphatase; Function Code: 1.6 Amino Acid Biosynthesis: Serine family; (serB).
  
 
 0.927
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.
