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

degQPeriplasmic pH-dependent serine endoprotease DegQ; Belongs to the peptidase S1C family. (455 aa)    
Predicted Functional Partners:
rseA
Anti-sigma-E factor RseA; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-E (RpoE). ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, DegS), then within the membrane itself (site-2 protease, S2P, RseP), while cytoplasmic proteases finish de [...]
  
 
 0.811
degS
Serine endoprotease DegS.
 
   
0.713
rseC
Protein RseC.
  
  
 0.682
ompA
Outer membrane protein A; With TolR probably plays a role in maintaining the position of the peptidoglycan cell wall in the periplasm. Acts as a porin with low permeability that allows slow penetration of small solutes; an internal gate slows down solute passage.
   
 
 0.662
pnp_1
Polyribonucleotide nucleotidyltransferase.
  
  
 0.635
yddG
Aromatic amino acid exporter YddG.
      
 0.594
rseB
Sigma-E factor regulatory protein RseB.
  
  
 0.579
yhcB_1
Inner membrane protein YhcB.
 
   
 0.567
tolC_2
Outer membrane protein TolC.
      
 0.567
glgA_1
Glycogen synthase; Synthesizes alpha-1,4-glucan chains using ADP-glucose.
      
 0.558
