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

hdeDHdeD protein; Escherichia coli K-12 ortholog: b3511; Escherichia coli O157:H7 ortholog: z4923. (190 aa)    
Predicted Functional Partners:
hdeB
Protein hdeB precursor; Required for optimal acid stress protection, which is important for survival of enteric bacteria in the acidic environment of the host stomach. Exhibits a chaperone-like activity at acidic pH by preventing the aggregation of many different periplasmic proteins. Belongs to the HdeB family.
  
  
 0.994
hdeA
Protein hdeA precursor; Required for optimal acid stress protection. Exhibits a chaperone-like activity only at low pH by suppressing non-specifically the aggregation of denaturated periplasmic proteins. Belongs to the HdeA family.
  
  
 0.993
xasA
Amino acid antiporter; Involved in glutamate-dependent acid resistance. Imports glutamate inside the cell while simultaneously exporting to the periplasm the GABA produced by GadA and GadB. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria (By similarity).
  
  
 0.982
slp
Outer membrane protein slp precursor; Escherichia coli K-12 ortholog: b3506; Escherichia coli O157:H7 ortholog: z4908.
  
  
 0.979
yhiE
Hypothetical protein yhiE; Regulates the expression of several genes involved in acid resistance. Required for the expression of gadA and gadBC, among others, regardless of media or growth conditions. Binds directly to the 20 bp GAD box found in the control regions of both loci (By similarity).
   
  
 0.979
yhiD
Hypothetical protein yhiD; Escherichia coli K-12 ortholog: b3508; Escherichia coli O157:H7 ortholog: z4920.
 
  
 0.978
gadB
Glutamate decarboxylase beta; Converts glutamate to gamma-aminobutyrate (GABA), consuming one intracellular proton in the reaction. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria (By similarity).
   
  
 0.945
gadA
Glutamate decarboxylase alpha; Converts glutamate to gamma-aminobutyrate (GABA), consuming one intracellular proton in the reaction. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria (By similarity).
   
  
 0.944
yhiX
Transcriptional regulator gadX; Positively regulates the expression of about fifteen genes involved in acid resistance such as gadA, gadB and gadC. Depending on the conditions (growth phase and medium), can repress gadW (By similarity).
  
  
 0.825
yhiF
Hypothetical transcriptional regulator yhiF; May act as a transcriptional regulator of dctA.
   
  
 0.792
