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

trpDProbable anthranilate phosphoribosyltransferase TrpD; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA). (370 aa)    
Predicted Functional Partners:
trpG
Possible anthranilate synthase component II TrpG (glutamine amidotransferase); 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 anthranilat [...]

trpE
Anthranilate synthase component I TrpE (glutamine amidotransferase); 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 [...]

trpC
Rv1611, (MTCY01B2.03), len: 272 aa. Probable trpC,indole-3-glycerol phosphate synthase. Similar to Q55508|SLR0546 hypothetical 33.0 kDa protein from synechocystis SP (295 aa), FASTA score: opt: 26, E(): 7.6e-32, (44.2% identity in 265 aa overlap); also similar to TRPC_AZOBR|P26938 ndole-3-glycerol-phosphate synthaseindole-3-glycerol-phosphate synthase from Azospirillum brasilense (262 aa), FASTA score: opt: 596,E(): 4.8e-30, (43.8% identity in 258 aa overlap). Equivalent to AL0499 13|MLCB1610_24 from Mycobacterium leprae (272 aa) (90.8% identity in 272 aa overlap). Contains indole-3-gl [...]

trpA
Probable tryptophan synthase, alpha subunit TrpA; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate.
 
  
 0.994
trpB
Tryptophan synthase, beta subunit TrpB; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
 
  
 0.991
mbtI
Isochorismate synthase MbtI; Involved in the incorporation of salicylate into the virulence-conferring salicylate-based siderophore mycobactin. Catalyzes the initial conversion of chorismate to yield the intermediate isochorismate (isochorismate synthase activity), and the subsequent elimination of the enolpyruvyl side chain to give salicylate (isochorismate pyruvate-lyase activity). In the absence of magnesium, MbtI displays a chorismate mutase activity and converts chorismate to prephenate.

pabB
Rv1005c, (MTCI237.22c), len: 458 aa (Start-site not certain). Probable PabD, para-aminobenzoate synthase component I. Similar to PABB_ECOLI|P05041 para-aminobenzoate synthase component I from Escherichia coli (453 aa), FASTA scores: opt: 589, E(): 1.8e-27, (40.7% identity in 268 aa overlap). Similar to M. tuberculosis Rv1609, Rv3215, Rv2386c.

hisA
Probable phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase HisA; Involved in both the histidine and tryptophan biosynthetic pathways; Belongs to the HisA/HisF family.

ctaE
Rv2193, (MTCY190.04), len: 203 aa. Probable ctaE,cytochrome c oxidase polypeptide III (cox3), with strong similarity to others e.g. COX3_SYNY3|Q06475 (29.8% identity in 225 aa overlap).

proC
Probable pyrroline-5-carboxylate reductase ProC (P5CR) (P5C reductase); Catalyzes the reduction of 1-pyrroline-5-carboxylate (PCA) to L-proline.
