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. (396 aa)    
Predicted Functional Partners:
trpC
N-(5'-phosphoribosyl)anthranilate isomerase; Similar to Escherichia coli tryptophan biosynthesis protein TrpC [includes: indole-3-glycerol phosphate synthase trpc or b1262 SWALL:TRPC_ECOLI (SWALL:P00909) (452 aa) fasta scores: E(): 1.6e-121, 69.93% id in 449 aa.
 
 0.999
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.
 0.999
trpG
Similar to Serratia marcescens anthranilate synthase component II TrpG SWALL:TRPG_SERMA (SWALL:P00900) (192 aa) fasta scores: E(): 6.3e-60, 85.34% id in 191 aa, and to Yersinia pestis anthranilate synthase component II TrpG or ypo2207 or y2050.1 SWALL:Q8ZEG6 (EMBL:AJ414151) (192 aa) fasta scores: E(): 5.4e-62, 84.89% id in 192 aa.
 
  
 0.996
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).
 
  
 0.984
trpE
Similar to Escherichia coli anthranilate synthase component I TrpE or b1264 SWALL:TRPE_ECOLI (SWALL:P00895) (520 aa) fasta scores: E(): 2.8e-154, 77.5% id in 520 aa.
 
  
 0.978
ehpC
Putative phenazine antibiotic biosynthesis protein; Similar to Pseudomonas aeruginosa PhzE and pa4214 SWALL:O33410 (EMBL:AF005404) (627 aa) fasta scores: E(): 1.2e-105, 45.65% id in 622 aa, and to Pantoea agglomerans EhpC SWALL:AAN40892 (EMBL:AF451953) (634 aa) fasta scores: E(): 6.8e-55, 37.82% id in 624 aa.
 
  
 0.974
tdcB
Putative threonine dehydratase catabolic; Similar to Escherichia coli, Escherichia coli O6, Escherichia coli O157:H7, and Shigella flexneri threonine dehydratase catabolic TdcB or b3117 or c3875 or z4469 or ecs3997 or sf3157 SWALL:THD2_ECOLI (SWALL:P05792) (329 aa) fasta scores: E(): 9.6e-33, 38.14% id in 312 aa, and to Thermotoga maritima threonine dehydratase catabolic tm0356 SWALL:Q9WYJ1 (EMBL:AE001716) (401 aa) fasta scores: E(): 6.1e-41, 41.32% id in 317 aa.
  
 0.928
ilvA
Threonine dehydratase biosynthetic; 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.
  
 0.928
serB
Phosphoserine phosphatase; Similar to Escherichia coli, Escherichia coli O157:H7, and Shigella flexneri phosphoserine phosphatase SerB or b4388 or z5989 or ecs5346 or sf4420 SWALL:SERB_ECOLI (SWALL:P06862) (322 aa) fasta scores: E(): 5.7e-81, 71.87% id in 320 aa.

pabB
Similar to Escherichia coli para-aminobenzoate synthase component I PabB or b1812 SWALL:PABB_ECOLI (SWALL:P05041) (453 aa) fasta scores: E(): 6.5e-119, 66.51% id in 433 aa.
