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.

spoIIGASporulation factor SpoIIGA; Probable aspartic protease that is responsible for the proteolytic cleavage of the RNA polymerase sigma E factor (SigE/spoIIGB) to yield the active peptide in the mother cell during sporulation. Responds to a signal from the forespore that is triggered by the extracellular signal protein SpoIIR. Belongs to the peptidase U4 family. (268 aa)    
Predicted Functional Partners:
spoIIE
Stage II sporulation protein E; Identified by similarity to SP:P37475; match to protein family HMM PF07228; match to protein family HMM TIGR02865.
  
  
 0.941
sigE
RNA polymerase sigma-E factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
  
 0.934
sigG
RNA polymerase sigma-G factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
  
 0.930
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.
