STRING protein interaction network
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:
some 3D structure is known or predicted
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
protein homology
Your Input:
Gene Fusion
fadRGntr family transcriptional regulator, negative regulator for fad regulon and positive regulator of faba; Multifunctional regulator of fatty acid metabolism Represses transcription of at least eight genes required for fatty acid transport and beta-oxidation including fadA, fadB, fadD, fadL and fadE . Activates transcription of at least three genes required for unsaturated fatty acid biosynthesis: fabA, fabB and iclR, the gene encoding the transcriptional regulator of the aceBAK operon encoding the glyoxylate shunt enzymes (239 aa)    
Predicted Functional Partners:
Tetr/acrr family transcriptional regulator, fatty acid biosynthesis regulator; Binds the promoter region of at least fabA and fabB, but probably not yqfA . Represses the transcription of fabA and fabB, involved in unsaturated fatty acid (UFA) biosynthesis . By controlling UFA production, FabR directly influences the physical properties of the membrane bilayer
3-hydroxyacyl-[acyl-carrier protein] dehydratase / trans-2-decenoyl-[acyl-carrier protein] isomerase; Necessary for the introduction of cis unsaturation into fatty acids. Catalyzes the dehydration of (3R)-3-hydroxydecanoyl-ACP to E- (2)-decenoyl-ACP and then its isomerization to Z-(3)-decenoyl-ACP. Can catalyze the dehydratase reaction for beta-hydroxyacyl-ACPs with saturated chain lengths up to 16:0, being most active on intermediate chain length. Is inactive in the dehydration of long chain unsaturated beta-hydroxyacyl-ACP
Beta-ketoacyl-[acyl carrier protein] synthase i; Catalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP. Specific for elongation from C-10 to unsaturated C-16 and C-18 fatty acids
Acyl coenzyme a dehydrogenase; Catalyzes the dehydrogenation of acyl-coenzymes A (acyl-CoAs) to 2-enoyl-CoAs, the first step of the beta-oxidation cycle of fatty acid degradation. Is required for E.coli to utilize dodecanoate or oleate as the sole carbon and energy source for growth
Involved in translocation of long-chain fatty acids across the outer membrane. It is a receptor for the bacteriophage T2. FadL may form a specific channel
Metj family transcriptional regulator, methionine regulon repressor; This regulatory protein, when combined with SAM (S- adenosylmethionine) represses the expression of the methionine regulon and of enzymes involved in SAM synthesis. It is also autoregulated
Acyl-coa synthetase (long-chain-fatty-acid--coa ligase); Catalyzes the esterification, concomitant with transport, of exogenous long-chain fatty acids into metabolically active CoA thioesters for subsequent degradation or incorporation into phospholipids. Activity is the highest with fatty acid substrates of > 10 carbon atoms . Is involved in the aerobic beta- oxidative degradation of fatty acids, which allows aerobic growth of E.coli on fatty acids as a sole carbon and energy source
Dna-binding transcriptional activator/ornithine decarboxylase inhibitor atoc; Member of the two-component regulatory system AtoS/AtoC. In the presence of acetoacetate, AtoS/AtoC stimulates the expression of the atoDAEB operon, leading to short chain fatty acid catabolism and activation of the poly-(R)-3-hydroxybutyrate (cPHB) biosynthetic pathway. Also induces the operon in response to spermidine . Involved in the regulation of motility and chemotaxis, via transcriptional induction of the flagellar regulon . AtoC acts by binding directly to the promoter region of the target genes . In [...]
Iclr family transcriptional regulator, acetate operon repressor; Regulation of the glyoxylate bypass operon (aceBAK), which encodes isocitrate lyase, malate synthase as well as isocitrate dehydrogenase kinase/phosphorylase. Glyoxylate disrupts the interaction with the promoter by favoring the inactive dimeric form. Pyruvate enhances promoter binding by stabilizing the tetrameric form
Laci family transcriptional regulator, gluconate utilization system gnt-i transcriptional repressor; Negative regulator for the gluconate utilization system GNT- I, the gntUKR operon
