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

spoIVBPeptidase; Derived by automated computational analysis using gene prediction method: Protein Homology. (315 aa)    
Predicted Functional Partners:
spo0A
Sporulation transcription factor Spo0A; May play the central regulatory role in sporulation. It may be an element of the effector pathway responsible for the activation of sporulation genes in response to nutritional stress. Spo0A may act in concert with Spo0H (a sigma factor) to control the expression of some genes that are critical to the sporulation process. Repressor of abrB, activator of the spoIIa operon. Binds the DNA sequence 5'-TGNCGAA-3' (0A box) (By similarity).
   
 0.972
sigK
RNA polymerase subunit sigma-70; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the sigma-70 factor family.
  
  
 0.839
gpr
GPR endopeptidase; Initiates the rapid degradation of small, acid-soluble proteins during spore germination; Belongs to the peptidase A25 family.
  
    0.831
spoVFB
Dipicolinate synthase subunit B; Involved in production of dipicolinic acid (pyridine-2,6-dicarboxylic acid, DPA) which is synthesized late in sporulation in the mother cell and accumulates in the spore; mutations in this gene result in a lack of DPA synthesis; presumably functions with SpoVFA to form the synthase enzyme; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
    0.826
spoIIAB
Anti-sigma F factor; Binds to sigma F and blocks its ability to form an RNA polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine residue. This phosphorylation may enable SpoIIAA to act as an anti- anti-sigma factor that counteracts SpoIIAB and thus releases sigma F from inhibition.
  
   
 0.815
SpoIIR
Stage II sporulation protein R; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
   
 0.803
spoIIAA
Anti-sigma F factor antagonist; In the phosphorylated form it could act as an anti-anti-sigma factor that counteracts SpoIIAB and thus releases sigma f from inhibition; Belongs to the anti-sigma-factor antagonist family.
 
   
 0.792
sigF_2
RNA polymerase sigma-F factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
  
   
 0.792
spoIVA
Stage IV sporulation protein B; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
   
 0.792
yabP
Sporulation protein YabP; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
   
 0.792
