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 (trpB); The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine. (404 aa)    
Predicted Functional Partners:
trpC
Indole-3-glycerol phosphate synthase/phosphoribosylanthranilate isomerase (trpC); Similar to SP:P18304 PID:149042 percent identity: 42.65; identified by sequence similarity; putative; Belongs to the TrpC family.
 
 0.999
trpA
Tryptophan synthase alpha subunit (trpA); 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
Anthranilate synthase component II (trpG); 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 [...]

trpF
Phosphoribosylanthranilate isomerase (trpF); Similar to GB:M83788 PID:149038 SP:P52563 percent identity: 41.23; identified by sequence similarity; putative; Belongs to the TrpF family.
  
  
 0.995
trpE
Anthranilate synthase component I (trpE); 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.

trpD
Anthranilate synthase component II (trpD); Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).
 
  
 0.989
glyA
Serine hydroxymethyltransferase (glyA); Catalyzes the reversible interconversion of serine and glycine with tetrahydromethanopterin (H4MPT) serving as the one-carbon carrier. The use of tetrahydrofolate (THF or H4PteGlu) as the pteridine substrate is 450-fold less efficient than that of H4MPT. Also exhibits a pteridine-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism. Thus, is able to catalyze the cleavage of L-allo-threonine and L-threo- beta-phenylserine; Belongs to the SHMT family.

MJ_1594
Phosphoserine phosphatase (serB); Similar to SP:P06862 GB:X03046 PID:42948 PID:537228 GB:U00096 percent identity: 39.80; identified by sequence similarity; putative.
  
 
 0.932
pssA
CDP-diacylglycerol--serine O-phosphatidyltransferase (pssA); Similar to GB:D38022 SP:P39823 PID:1065993 GB:AL009126 percent identity: 43.51; identified by sequence similarity; putative; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.

MJ_0672
Membrane bound transport protein, putative; Similar to GB:L42023 PID:1005433 PID:1220685 PID:1204859 SP:Q57486 percent identity: 40.00; identified by sequence similarity; putative.
