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

degQSerine endoprotease DegQ; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the peptidase S1C family. (455 aa)    
Predicted Functional Partners:
rseA
anti-RNA polymerase sigma factor SigE; 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 protea [...]

ompA_1
Membrane protein; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the outer membrane OOP (TC 1.B.6) superfamily.
   
 
 0.645
ompA_2
Membrane protein; OmpA is believed to be a porin, involved in diffusion of nonspecific small solutes across the outer membrane. It is the most abundant integral protein of the outer membrane of E. coli, and it is known to play a role as a phage receptor, a mediator of F-factor dependent conjugation, and in maintaining the structural shape of the outer membrane; 3a; II*; G; d; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the outer membrane OOP (TC 1.B.6) superfamily.
   
 
 0.645
pnp
Polynucleotide phosphorylase/polyadenylase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
  
  
 0.629
degS_2
Serine endoprotease; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
    
0.621
mdtK
Multidrug transporter; Multidrug efflux pump that functions probably as a Na(+)/drug antiporter; Belongs to the multi antimicrobial extrusion (MATE) (TC 2.A.66.1) family. MdtK subfamily.
   
  
 0.620
fimH_2
Fimbrial protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
      
 0.575
pspC
Transcriptional regulator; With PsbB forms toxin/antitoxin pair; activates the psp operon in response to phage infection, exposure to ethanol or osmotic shock; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.572
groEL
Molecular chaperone GroEL; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
  
 
 0.568
secY
Preprotein translocase subunit SecY; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.
