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 subunit beta; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine. (401 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.
 0.999
trpF
Phosphoribosylanthranilate isomerase; IMG reference gene:2512957100; PFAM: N-(5'phosphoribosyl)anthranilate (PRA) isomerase; Belongs to the TrpF family.
  
 0.999
trpC
IMG reference gene:2512953916; PFAM: Indole-3-glycerol phosphate synthase; Belongs to the TrpC 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).
  
 0.984
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 concent [...]

trpG
Anthranilate synthase, component II; IMG reference gene:2512953918; PFAM: Glutamine amidotransferase class-I; TIGRFAM: glutamine amidotransferase of anthranilate synthase or aminodeoxychorismate synthase.
  
 0.941
RSP_2252
Threonine dehydratase; IMG reference gene:2512954181; PFAM: Pyridoxal-phosphate dependent enzyme.
  
 0.941
SHMT
Serine hydroxymethyltransferase protein; 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.

RSP_0245
Serine-pyruvate aminotransferase/aspartate aminotransferase; IMG reference gene:2512955251; PFAM: Aminotransferase class-V.
  
 
 0.909
serB
Phosphoserine phosphatase; IMG reference gene:2512956396; PFAM: haloacid dehalogenase-like hydrolase; TIGRFAM: Haloacid Dehalogenase superfamily, subfamily IB, phosphoserine phosphatase-like; phosphoserine phosphatase SerB.
