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

trpGAnthranilate 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 [...] (197 aa)    
Predicted Functional Partners:
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).

trpB
Tryptophan synthase beta subunit (trpB); The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
 
  
 0.997
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.
 
  
 0.994
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.
  
 0.994
aroQ
Chorismate mutase/prephenate dehydratase (pheA); Catalyzes the conversion of chorismate into prephenate via a Claisen rearrangement.
  
 
 0.972
aroC
Chorismate synthase (aroC); 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.

MJ_0239
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ0239.
       0.917
hisH
Imidazole glycerol phosphate synthase, subunit H (hisH); IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF (By similarity).
