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
Your Input:
trpEComponent I of anthranilate synthase; 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 conce [...] (520 aa)

smtAPutative S-adenosyl-L-methionine-dependent methyltransferase; Catalyzes the methylation of 5-carboxymethoxyuridine (cmo5U) to form 5-methoxycarbonylmethoxyuridine (mcmo5U) at position 34 in tRNAs. Four tRNAs (tRNA(Ala1), tRNA(Ser1), tRNA(Pro3) and tRNA(Thr4)) are fully modified with mcmo5U in stationary-phase E.coli. Also present at low frequency in tRNA(Leu3) and tRNA(Val1). (261 aa)
mdfAMultidrug efflux system protein; Efflux pump driven by the proton motive force. Confers resistance to a broad spectrum of chemically unrelated drugs. Confers resistance to a diverse group of cationic or zwitterionic lipophilic compounds such as ethidium bromide, tetraphenylphosphonium, rhodamine, daunomycin, benzalkonium, rifampicin, tetracycline, puromycin, and to chemically unrelated, clinically important antibiotics such as chloramphenicol, erythromycin, and certain aminoglycosides and fluoroquinolones. Overexpression results in isopropyl-beta-D- thiogalactopyranoside (IPTG) exclusi [...] (410 aa)
flcFluoride efflux channel, dual topology membrane protein; Important for reducing fluoride concentration in the cell, thus reducing its toxicity. (127 aa)
entCIsochorismate synthase 1; Involved in the biosynthesis of the siderophore enterobactin (macrocyclic trimeric lactone of N-(2,3-dihydroxybenzoyl)-serine). Catalyzes the reversible conversion of chorismate to isochorismate. (391 aa)
mnmHtRNA 2-selenouridine synthase; Involved in the post-transcriptional modification of the uridine at the wobble position (U34) of tRNA(Lys), tRNA(Glu) and tRNA(Gln). Catalyzes the conversion of 2-thiouridine (S2U-RNA) to 2-selenouridine (Se2U-RNA). Acts in a two-step process involving geranylation of 2-thiouridine (S2U) to S-geranyl-2-thiouridine (geS2U) and subsequent selenation of the latter derivative to 2-selenouridine (Se2U) in the tRNA chain. (364 aa)
tyrAChorismate mutase-T and prephenate dehydrogenase; Protein involved in L-phenylalanine biosynthetic process and tyrosine biosynthetic process. (373 aa)
pheAChorismate mutase and prephenate dehydratase, P-protein; Catalyzes the Claisen rearrangement of chorismate to prephenate and the decarboxylation/dehydration of prephenate to phenylpyruvate. (386 aa)
menFIsochorismate synthase 2; Catalyzes the conversion of chorismate to isochorismate. Can also catalyze the reverse reaction, but with a lower efficiency. (431 aa)
yegQPutative peptidase; Belongs to the peptidase U32 family. (453 aa)
cmoBtRNA (cmo5U34)-carboxymethyltransferase, carboxy-SAM-dependent; Catalyzes carboxymethyl transfer from carboxy-S-adenosyl-L- methionine (Cx-SAM) to 5-hydroxyuridine (ho5U) to form 5- carboxymethoxyuridine (cmo5U) at position 34 in tRNAs. Can also catalyze the SAM-dependent methylation of ho5U, with much lower efficiency. (323 aa)
cmoAcarboxy-SAM synthase; Catalyzes the conversion of S-adenosyl-L-methionine (SAM) to carboxy-S-adenosyl-L-methionine (Cx-SAM); Belongs to the class I-like SAM-binding methyltransferase superfamily. Cx-SAM synthase family. (247 aa)
pabBAminodeoxychorismate synthase, subunit I; Part of a heterodimeric complex that catalyzes the two-step biosynthesis of 4-amino-4-deoxychorismate (ADC), a precursor of p- aminobenzoate (PABA) and tetrahydrofolate. In the first step, a glutamine amidotransferase (PabA) generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by aminodeoxychorismate synthase (PabB) to produce ADC. PabB, in the absence of PabA, can catalyze the formation of ADC in the presence of exogenous ammonia. (453 aa)
ydcPPutative peptidase; Responsible for the formation of the 5-hydroxycytidine modification at the C2501 position (ho5C2501) of 23S rRNA. May be a Fe- S protein that catalyzes ho5C2501 formation using prephenate as a hydroxyl group donor. (653 aa)

Catalyzes the methyl transfer from S-adenosyl-L-methionine to the 2'-OH of the wobble nucleotide. Recognition of the target requires a pyridine at position 34 and N(6)-(isopentenyl)-2-methylthioadenosine at position 37. (157 aa)
ubiCChorismate pyruvate-lyase; Removes the pyruvyl group from chorismate, with concomitant aromatization of the ring, to provide 4-hydroxybenzoate (4HB) for the ubiquinone pathway. (165 aa)

prfBPeptide chain release factor RF-2; Peptide chain release factor 2 directs the termination of translation in response to the peptide chain termination codons UGA and UAA. Acts as a peptidyl-tRNA hydrolase. In the presence of truncated mRNA in the 70S ribosome, ArfA and RF2 interact such that the GGQ peptide hydrolysis motif of RF2 rises into the peptidyl-transferase center and releases the ribosome. Recruited by ArfA to rescue stalled ribosomes in the absence of a normal stop codon. (365 aa)
