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

degQSimilar to E. coli serine endoprotease (AAC76266.1); Blastp hit to AAC76266.1 (455 aa), 89% identity in aa 1 - 455; Belongs to the peptidase S1C family. (455 aa)    
Predicted Functional Partners:
degS
Periplasmic serine endoprotease; Similar to E. coli protease (AAC76267.1); Blastp hit to AAC76267.1 (355 aa), 91% identity in aa 1 - 355.

rseA
Anti sigma E (sigma 24) factor, negative regulator; 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 cytop [...]

arcB
Sensory histidine kinase in two-component regulatory system with ArcA; Senses redox conditions; similar to E. coli aerobic respiration sensor-response protein; histidine protein kinase/phosphatase, sensor for arcA (AAC76242.1); Blastp hit to AAC76242.1 (776 aa), 93% identity in aa 1 - 776.

ompA
Putative membrane component hydrogenase; 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.
   
 
 0.663
yhcM
Putative ATPase; Reduces the stability of FtsZ polymers in the presence of ATP.
     
 0.585
mopA
Chaperone Hsp60 with peptide-dependent ATPase activity; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
  
 
 0.554
yaeT
Putative outer membrane antigen; Part of the outer membrane protein assembly complex, which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. Constitutes, with BamD, the core component of the assembly machinery.
  
  
 0.540
pnp
Polynucleotide phosphorylase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. Is a global regulator of virulence and persistency.
  
  
 0.539
fkpA
Similar to E. coli FKBP-type peptidyl-prolyl cis-trans isomerase (rotamase) (AAC76372.1); Blastp hit to AAC76372.1 (270 aa), 90% identity in aa 1 - 270.
   
 
 0.526
yhcB
Putative periplasmic protein; Similar to E. coli orf, hypothetical protein (AAC76265.1); Blastp hit to AAC76265.1 (134 aa), 97% identity in aa 1 - 134.
