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

aprESerine alkaline protease (subtilisin E); Subtilisin is an extracellular alkaline serine protease, it catalyzes the hydrolysis of proteins and peptide amides; Belongs to the peptidase S8 family. (381 aa)    
Predicted Functional Partners:
nprE
Extracellular neutral metalloprotease; Extracellular zinc metalloprotease; Belongs to the peptidase M4 family.
 
  
 0.986
nprB
Extracellular neutral protease B; Protease able to cleave casein in vitro. Belongs to the peptidase M4 family.
 
  
 0.940
mpr
Extracellular glutamyl-endopeptidase; Evidence 1c: Function experimentally demonstrated in the studied genus; Product type e: enzyme; Belongs to the peptidase S1B family.
  
  
 0.920
amyE
Alpha-amylase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the glycosyl hydrolase 13 family.
   
  
 0.916
degS
Two-component sensor histidine kinase; Member of the two-component regulatory system DegS/DegU, which plays an important role in the transition growth phase. Involved in the control of expression of different cellular functions, including production of degradative enzymes such as the neutral and alkaline proteases, flagellum formation and biofilm formation. Acts as both a protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to DegU, and a protein phosphatase that dephosphorylates phospho-DegU.
      
 0.845
estB
Secreted esterase / lipase; An esterase which preferentially hydrolyzes triacylglyceride substrates with short chain fatty acids (less than C10) with the maximum activity towards tricaprylin (C8:0). Active against p- nitrophenylesters with fatty acid chain lengths from C6 to C18.
  
   
 0.799
sacB
Levansucrase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
      
 0.754
scoC
HTH-type transcriptional regulator Hpr; Negative regulator of protease production and sporulation. Acts by binding directly to the promoter of protease genes (aprE and nprE), and by repressing oligopeptide permease operons (appABCDF and oppABCDF), thereby preventing uptake of oligopeptides required for initiation of sporulation. Acts with SinR as a corepressor of epr expression.
   
  
 0.737
phy
Phytase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
  
  
 0.721
htrA
Membrane bound serine protease Do, quality control protease (heat-shock protein); Degrades abnormal exported proteins and responsible for the propeptide processing of a natural pro-protein and for the maturation of a native protein. It also plays a prominent role in stress (heat shock, ethanol, puromycin and NaCl) resistance during active exponential growth (Probable); Belongs to the peptidase S1C family.
