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

ybdBOrf, hypothetical protein; Required for optimal enterobactin synthesis. Acts as a proofreading enzyme that prevents EntB misacylation by hydrolyzing the thioester bound existing between EntB and wrongly charged molecules. Belongs to the thioesterase PaaI family. (137 aa)    
Predicted Functional Partners:
entB
2,3-dihydro-2,3-dihydroxybenzoate synthetase, isochroismatase; 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 o [...]

entA
2,3-dihydro-2,3-dihydroxybenzoate dehydrogenase, enterochelin biosynthesis; Residues 1 to 248 of 248 are 99.19 pct identical to residues 1 to 248 of 248 from Escherichia coli K-12 Strain MG1655: B0596.
  
  
 0.998
entE
2,3-dihydroxybenzoate-AMP ligase; 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. EntE proccesses via a two-step adenylation-ligation reaction (bi-uni-uni-bi ping-pong mechanism). First, it catalyzes the activation of the carboxylate group of 2,3-dihydroxy-benzoate (DHB), via a reversible ATP-dependent pyrophosphate excha [...]

entC
Isochorismate hydroxymutase 2, enterochelin biosynthesis; 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.
 
  
 0.955
entF
ATP-dependent serine activating enzyme (may be part of enterobactin synthase as component F); Activates the carboxylate group of L-serine via ATP-dependent PPi exchange reactions to the aminoacyladenylate, preparing that molecule for the final stages of enterobactin synthesis. Holo-EntF acts as the catalyst for the formation of the three amide and three ester bonds present in the cyclic (2,3-dihydroxybenzoyl)serine trimer enterobactin, using seryladenylate and acyl-holo-EntB (acylated with 2,3-dihydroxybenzoate by EntE) (By similarity); Belongs to the ATP-dependent AMP-binding enzyme f [...]

fepA
Outer membrane receptor for ferric enterobactin (enterochelin) and colicins B and D; Residues 1 to 746 of 746 are 99.19 pct identical to residues 1 to 746 of 746 from Escherichia coli K-12 Strain MG1655: B0584.
   
    0.879
fepB
Ferric enterobactin (enterochelin) binding protein; Residues 1 to 318 of 318 are 98.42 pct identical to residues 1 to 318 of 318 from Escherichia coli K-12 Strain MG1655: B0592.
  
    0.747
entD
Enterobactin synthetase component D; 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. Plays an essential role in the assembly of the enterobactin by catalyzing the transfer of the 4'-phosphopantetheine (Ppant) moiety from coenzyme A to the apo- domains of both EntB (ArCP domain) and EntF (PCP domain) to yield their holo-fo [...]
