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

spoIIGA
Protease processing pro-sigma-E; 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.
   
    0.525
spoIIAB
Anti-sigma factor (antagonist of sigma(F)) and serine kinase; 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.

refZ
Regulator of FtsZ; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator.
   
    0.502
sigE
RNA polymerase sporulation-specific sigma-29 factor (sigma-E); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of sporulation specific genes.
   
    0.501
glgD
Glucose-1-phosphate adenylyltransferase (ADP-glucose pyrophosphorylase) beta subunit; Required for the synthesis of glycogen; Belongs to the bacterial/plant glucose-1-phosphate adenylyltransferase family.
   
    0.501
glgC
Glucose-1-phosphate adenylyltransferase (ADP-glucose pyrophosphorylase) subunit alpha; Involved in the biosynthesis of ADP-glucose, a building block required for the elongation reactions to produce glycogen. Catalyzes the reaction between ATP and alpha-D-glucose 1-phosphate (G1P) to produce pyrophosphate and ADP-Glc.
   
    0.501
glgB
1,4-alpha-glucan branching enzyme; Catalyzes the formation of the alpha-1,6-glucosidic linkages in glycogen by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position.
   
    0.499
sspM
Small acid-soluble spore protein; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type cp: cell process.
