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 subunit; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine. (418 aa)    
Predicted Functional Partners:
trpC
Indole-3-glycerol phosphate synthase; Identified by match to protein family HMM PF00218; Belongs to the TrpC family.
 
 0.999
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
trpF
N-(5'phosphoribosyl)anthranilate isomerase; Identified by match to protein family HMM PF00697; Belongs to the TrpF family.
 
  
 0.973
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).
 
  
 0.967
sync_2663
Para-aminobenzoate synthase component II; Identified by match to protein family HMM PF00117; match to protein family HMM TIGR00566.
 
  
 0.947
ilvA
Threonine dehydratase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA.
  
 0.945
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
     
 0.927
sync_0462
Putative anthranilate synthase component I; Identified by similarity to SP:P20579; match to protein family HMM PF00425; match to protein family HMM PF04715.
 
  
 0.906
sync_1566
Serine:pyruvate/alanine:glyoxylate aminotransferase; Identified by match to protein family HMM PF00266; spt, agt.
    
 0.906
cobC
Possible alpha-ribazole-5-P phosphatase; Identified by match to protein family HMM PF00300; Belongs to the phosphoglycerate mutase family.
