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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
acpHAcyl carrier protein phosphodiesterase; Converts holo-ACP to apo-ACP by hydrolytic cleavage of the phosphopantetheine prosthetic group from ACP (193 aa)    
Predicted Functional Partners:
Pantothenate kinase; Protein involved in coenzyme A biosynthetic process; Belongs to the prokaryotic pantothenate kinase family
Holo-[acyl-carrier-protein] synthase; Transfers the 4'-phosphopantetheine moiety from coenzyme A to the 'Ser-36' of acyl-carrier-protein; Belongs to the P-Pant transferase superfamily. AcpS family
Enterobactin synthase component B; Involved in the biosynthesis of the siderophore enterobactin (enterochelin), which is a macrocyclic trimeric lactone of N-(2,3-dihydroxybenzoyl)-serine. The serine trilactone serves as a scaffolding for the three catechol functionalities that provide hexadentate coordination for the tightly ligated iron(2+) atoms. EntB is a bifunctional protein that serves as an isochorismate lyase and an aryl carrier protein (ArCP). Catalyzes the conversion of isochorismate to 2,3-dihydro-2,3- dihydroxybenzoate (2,3-diDHB), the precursor of 2,3- dihydroxybenzoate (DH [...]
Acyl carrier protein; Carrier of the growing fatty acid chain in fatty acid biosynthesis; Belongs to the acyl carrier protein (ACP) family
4'-phosphopantetheinyl transferase AcpT; May be involved in an alternative pathway for phosphopantetheinyl transfer and holo-ACP synthesis in E.coli. The native apo-protein substrate is unknown. Is able to functionally replace AcpS in vivo but only when expressed at high levels
Nucleoside triphosphate pyrophosphohydrolase; Involved in the regulation of bacterial cell survival under conditions of nutritional stress. Regulates the type II MazE-MazF toxin-antitoxin (TA) system which mediates programmed cell death (PCD). This is achieved by lowering the cellular concentration of (p)ppGpp produced by RelA under amino acid starvation, thus protecting the cell from the toxicity of MazF. Reduction of (p)ppGpp can be achieved by direct degradation of (p)ppGpp or by degradation of NTPs, which are substrates for (p)ppGpp synthesis by RelA; Belongs to the nucleoside trip [...]
Phosphopantetheine adenylyltransferase; Reversibly transfers an adenylyl group from ATP to 4'- phosphopantetheine, yielding dephospho-CoA (dPCoA) and pyrophosphate. CoA is not a substrate for the enzyme; Belongs to the bacterial CoaD family
Coenzyme A biosynthesis bifunctional protein CoaBC; Catalyzes two steps in the biosynthesis of coenzyme A. In the first step cysteine is conjugated to 4'-phosphopantothenate to form 4-phosphopantothenoylcysteine. In the second the latter compound is decarboxylated to form 4'- phosphopantotheine; In the C-terminal section; belongs to the PPC synthetase family
Acetate CoA-transferase YdiF; CoA transferase having broad substrate specificity for short-chain acyl-CoA thioesters with the activity decreasing when the length of the carboxylic acid chain exceeds four carbons. May play a role in short-chain fatty acid metabolism in E.coli (By similarity); Belongs to the 3-oxoacid CoA-transferase family
S-adenosylmethionine:tRNA ribosyltransferase-isomerase; Transfers and isomerizes the ribose moiety from AdoMet to the 7-aminomethyl group of 7-deazaguanine (preQ1-tRNA) to give epoxyqueuosine (oQ-tRNA); Belongs to the QueA family
