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

bacGPhenylalanine aminotransferase forming tetrahydrotyrosine in bacilysin synthesis; Part of the bacABCDEF operon responsible for the biosynthesis of the nonribosomally synthesized dipeptide antibiotic bacilysin, composed of L-alanine and L-anticapsin. Bacilysin is an irreversible inactivator of the glutaminase domain of glucosamine synthetase. Catalyzes the reductive amination of the C2 ketone of tetrahydro-hydroxyphenylpyruvate (H4HPP), with L-Phe as an amino donor, to yield tetrahydrotyrosine (H4Tyr) diastereomer. D-Phe is not an effective amino donor. BacF associated to BacG converts [...] (399 aa)    
Predicted Functional Partners:
bacC
Bacilysin biosynthesis oxidoreductase; Part of the bacABCDEFG operon responsible for the biosynthesis of bacilysin, an irreversible inactivator of the glutaminase domain of glucosamine synthetase. Catalyzes the dehydrogenation of the C7-hydroxyl group in the 4S-tetrahydrotyrosine (4S-H4Tyr) to yield anticapsin (epoxycyclohexanonyl-Ala). It is not able to oxidize the 4R-H4Tyr diastereomer and the dihydrobacilysin dipeptide (L-Ala-4S-H4Tyr dipeptide).

bacE
Efflux protein for bacilysin excretion, self-protection against bacilysin; Part of the bacilysin biosynthesis operon. May be involved in self-resistance to bacilysin by permitting efflux of this antibiotic.
  
  
 0.994
bacB
Isomerase component of bacilysin (l-alanine-[2,3-epoxycyclohexano-4]-l-alanine) synthetase; Part of the bacABCDEF operon responsible for the biosynthesis of the nonribosomally synthesized dipeptide antibiotic bacilysin, composed of L-alanine and L-anticapsin. Bacilysin is an irreversible inactivator of the glutaminase domain of glucosamine synthetase. BacB catalyzes the allylic isomerization of the endocyclic-delta(4),delta(8)-7R-dihydro- hydroxyphenylpyruvate (en-H2HPP) to generate a mixture of 3E,7R- and 3Z, 7R-olefins (E/Z ration of 3/1) of the exocyclic-delta(3),delta(5)- dihydro-h [...]

ldh
L-lactate dehydrogenase; Catalyzes the conversion of lactate to pyruvate.
  
 
 0.983
bacD
Alanine-anticapsin ligase; Part of the bacABCDEFG operon responsible for the biosynthesis of bacilysin, an irreversible inactivator of the glutaminase domain of glucosamine synthetase. Catalyzes the formation of alpha-dipeptides from various L-amino acids in the presence of ATP. In vivo catalyzes the ligation of L-alanine and L-anticapsin (epoxycyclohexanonyl-Ala) to produce the final bacilysin antibiotic (L- Ala-L-4S-cyclohexenonyl-Ala dipeptide). The substrate specificity is restricted to small amino acids such as L-Ala, for the N-terminal end of the dipeptide, whereas a wide range o [...]

bacH
Cyclohexenol-containing tetrahydro-4-hydroxyphenylpyruvate H(4)HPP in bacilysin synthesis; Along with the bacABCDEF operon, BacG is involved in the biosynthesis of the nonribosomally synthesized dipeptide antibiotic bacilysin, composed of L-alanine and L-anticapsin. Bacilysin is an irreversible inactivator of the glutaminase domain of glucosamine synthetase. BacG catalyzes the stereoselective reduction of exocyclic-delta(3),delta(5)-dihydro-hydroxyphenylpyruvate (ex-H2HPP), adding a pro-S hydride equivalent to C4 position to yield tetrahydro-hydroxyphenylpyruvate (H4HPP). Although the [...]

bacA
Bacilysin biosynthesis protein, dehydratase; Part of the bacABCDEF operon responsible for the biosynthesis of the nonribosomally synthesized dipeptide antibiotic bacilysin, composed of L-alanine and L-anticapsin. Bacilysin is an irreversible inactivator of the glutaminase domain of glucosamine synthetase. BacA is an unusual prephenate decarboxylase that avoids the typical aromatization of the cyclohexadienol ring of prephenate. BacA catalyzes the protonation of prephenate (1-carboxy-4-hydroxy- alpha-oxo-2,5-cyclohexadiene-1-propanoic acid) at C6 position, followed by a decarboxylation [...]

gabR
Transcriptional regulator (GntR/MocR family) with PLP binding site; Activates the transcription of the gabTD operon. Is also a repressor of its own expression, both in the presence and absence of GABA. Binds specifically to the DNA region overlapping the -35 region of the gabT promoter and the -10 and +1 regions of the gabR promoter. Principally regulates the utilization of gamma-aminobutyrate. In the C-terminal section; belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family.
