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

spoIIQForespore protein required for alternative engulfment; Involved in forespore engulfment and required for anchoring membrane proteins on the forespore side of the septal membrane. Forms a channel with SpoIIIAH that is open on the forespore end and closed (or gated) on the mother cell end. This allows sigma-E-directed gene expression in the mother-cell compartment of the sporangium to trigger the activation of sigma-G forespore-specific gene expression by a pathway of intercellular signaling. (283 aa)    
Predicted Functional Partners:
spoIIIAH
Stage III sporulation ratchet engulfment protein; Involved in forespore engulfment. Forms a channel with SpoIIIAH that is open on the forespore end and closed (or gated) on the mother cell end. This allows sigma-E-directed gene expression in the mother-cell compartment of the sporangium to trigger the activation of sigma-G forespore-specific gene expression by a pathway of intercellular signaling.

spoIID
Autolysin required for complete dissolution of the asymmetric septum (stage II sporulation); May act at the level of sigma-G activity or its stability. SpoIID is probably required for engulfment.
 
  
 0.975
spoIIP
Spore autolysin (stage II sporulation); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type cp: cell process.
  
  
 0.968
spoIIIAA
ATP-binding stage III sporulation protein; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type cp: cell process.
   
  
 0.961
spoIVFA
Regulator of SpoIVFB (stage IV sporulation); Implicated in the coupling of mother cell to forespore gene expression. Required for spore formation at 37 degrees Celsius, but not at 30 degrees Celsius. SpoIVFA plays a central role in both maintaining the SpoIVFA/BofA/SpoIVFB complex and anchoring it to the outer forespore membrane. SpoIVFA brings BofA into close proximity to SpoIVFB, allowing BofA to inhibit SpoIVFB. Increased accumulation of SpoIVFA seems to inhibit the activity of SpoIVFB and thus regulates the activation of sigma-K.
  
  
 0.941
spoIIIAG
Stage III sporulation engulfment assembly protein; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type cp: cell process.
   
  
 0.931
spoIIE
SpoIIAA-phosphate serine phosphatase; Normally needed for pro-sigma E processing during sporulation but can be bypassed in vegetative cells. Activates SpoIIAA by dephosphorylation.
  
  
 0.929
cotE
Morphogenic spore protein; Morphogenic protein required for the assembly of the outer coat of the endospore. Is also a regulatory protein for the expression of cotA, cotB, cotC, cotH and other genes encoding spore outer coat proteins.
  
  
 0.929
spoIIM
Autolysin component for dissolution of the septal cell wall (stage II sporulation); Required for complete septum migration and engulfment of the forespore compartment during sporulation. Required for stabilizing and recruiting of SpoIIP to the septal membrane.
   
  
 0.925
spoVID
Morphogenetic spore protein (stage VI sporulation); Required for assembly of a normal spore coat. May be a component of the innermost layer of the spore coat that aids in its adherence to the prespore.
