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

degRActivation of degradative enzymes (aprE, nprE, sacB) production or activity; Stabilizes the phosphorylated form of DegU, leading to enhanced production of levansucrase, alkaline protease, and neutral protease. (60 aa)    
Predicted Functional Partners:
degQ
Pleiotropic regulator; Stimulates the phosphotransfer from phospho-DegS to DegU. Affects protease and levansucrose production.
      
 0.849
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.
      
 0.847
sigD
RNA polymerase sigma-28 factor (sigma-D); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This alternative sigma factor is required for the transcription of the flagellin and motility genes as well as for wild- type chemotaxis.
   
  
 0.633
mecA
Adaptor protein controlling oligomerization of the AAA+ protein ClpC; Enables the recognition and targeting of unfolded and aggregated proteins to the ClpC protease or to other proteins involved in proteolysis. Acts negatively in the development of competence by binding ComK and recruiting it to the ClpCP protease. When overexpressed, inhibits sporulation. Also involved in Spx degradation by ClpC.
   
  
 0.576
sacB
Levansucrase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
      
 0.573
ypzA
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
    0.523
yplP
Transcriptional enhancer; May play a role in cold adaptation.
      
 0.485
levB
Endolevanase; Catalyzes the degradation of levan mainly into levanbiose (difructose). Is not active on sucrose; Belongs to the glycosyl hydrolase 32 family.
      
 0.483
sacY
Transcriptional antiterminator; In the presence of sucrose, SacY is activated and prevents premature termination of transcription by binding to a RNA- antiterminator (RAT) sequence (partially overlapping with the terminator sequence) located upstream of the sacB gene. Formation of the SacY-RAT complex prevents alternative formation of the terminator, allowing transcription of the sacB gene. In the absence of sucrose, inhibition of SacY activity by SacX leads to termination of transcription; Belongs to the transcriptional antiterminator BglG family.
