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:
some 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

fabA3-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 (172 aa)    
Predicted Functional Partners:
fabZ
(3R)-hydroxymyristol acyl carrier protein dehydratase; Involved in unsaturated fatty acids biosynthesis. Catalyzes the dehydration of short chain beta-hydroxyacyl-ACPs and long chain saturated and unsaturated beta-hydroxyacyl-ACPs
   
 
 0.995
fabB
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
 
 0.994
fabI
Enoyl-[acyl-carrier-protein] reductase, nadh-dependent; Catalyzes the reduction of a carbon-carbon double bond in an enoyl moiety that is covalently linked to an acyl carrier protein (ACP). Involved in the elongation cycle of fatty acid which are used in the lipid metabolism and in the biotin biosynthesis
    
 0.991
acpP
Acyl carrier protein (acp); Carrier of the growing fatty acid chain in fatty acid biosynthesis
  
 
 0.990
fabG
3-oxoacyl-[acyl-carrier-protein] reductase FabG; Catalyzes the NADPH-dependent reduction of beta-ketoacyl-ACP substrates to beta-hydroxyacyl-ACP products, the first reductive step in the elongation cycle of fatty acid biosynthesis
  
 0.989
fabD
Malonyl CoA-acyl carrier protein transacylase; Enzyme; Fatty acid and phosphatidic acid biosynthesis; Belongs to the FabD family
 
 
 0.976
fabH
Beta-ketoacyl-[acyl carrier protein] synthase iii; Catalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP. Catalyzes the first condensation reaction which initiates fatty acid synthesis and may therefore play a role in governing the total rate of fatty acid production. Possesses both acetoacetyl-ACP synthase and acetyl transacylase activities. Has some substrate specificity for acetyl-CoA. Its substrate specificity determines the biosynthesis of straight-chain of fatty acids instead of branched-chain
  
 
 0.951
fabF
Beta-ketoacyl-[acyl carrier protein] synthase ii; Catalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP. Has a preference for short chain acid substrates and may function to supply the octanoic substrates for lipoic acid biosynthesis
 
  
 0.933
fadR
Gntr 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
      
 0.913
fabR
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
