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

sigIRNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of cell wall metabolism in response to heat stress. Acts by regulating the expression of genes such as bcrC, mreBH and lytE. Also plays a role in survival at low temperatures. Belongs to the sigma-70 factor family. SigI subfamily. (251 aa)    
Predicted Functional Partners:
rsgI
sigmaI modulating factor; Anti-sigma factor for SigI. Negatively regulates SigI activity through direct interaction.
 
 
 0.999
flgM
Anti-sigma factor repressor of sigma(D)-dependent transcription; Allows the coupling of early and late flagellar synthesis through the repression of RNA polymerase sigma-D factor-dependent transcription.
  
 
 0.841
sigH
RNA polymerase sigma-30 factor (sigma(H)); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in the transition to post- exponential phase in the beginning of sporulation. It is also required for transcription of several stationary phase genes.

cheV
Coupling protein and response regulator for CheA activity in response to attractants (chemotaxis); Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. Chemotaxis involves both a phosphorylation-dependent excitation and a methylation-dependent adaptation. CheV and CheW are involved in the coupling of the methyl- accepting chemoreceptors to the central two-component kinase CheA; they are both necessary for efficient chemotaxis. Moreover, CheA-dependent phosphorylation of CheV is required for adaptation to attractants during B.subtilis chemotaxis.

mreBH
Cell-shape determining protein; Forms membrane-associated dynamic filaments that are essential for cell shape determination. Acts by regulating cell wall synthesis and cell elongation, and thus cell shape. A feedback loop between cell geometry and MreBH localization may maintain elongated cell shape by targeting cell wall growth to regions of negative cell wall curvature (By similarity). Filaments rotate around the cell circumference in concert with the cell wall synthesis enzymes. The process is driven by the cell wall synthesis machinery and does not depend on MreBH polymerization.

sigM
RNA polymerase ECF (extracytoplasmic function)-type sigma factor (sigma(M)); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by a cognate anti-sigma factor (YhdL) until released. This sigma factor is involved in the maintenance of membrane and cell wall integrity in response to environmental stresses including salt, acid, ethanol and antibiotics stress. Partially regulates transcription from a number of genes including disA.
   
  
 0.763
lytE
Cell wall hydrolase; Cell wall hydrolase that cleaves gamma-D-glutamate-meso- diaminopimelate bonds in peptidoglycan (By similarity). Seems to play a role in cell separation during vegetative growth.
   
  
 0.756
rpoB
RNA polymerase (beta subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.744
flgB
Flagellar component of cell-proximal portion of basal-body rod; Structural component of flagellum, the bacterial motility apparatus. Part of the rod structure of flagellar basal body.
  
 
 0.719
fliY
Flagellar motor switching and energizing phosphatase; Component of the flagellar switch. Binds CheY-P and increases its hydrolysis rate in vitro. May function constitutively to remove CheY-P around the flagellar switch to maintain an optimal level of CheY-P whereas CheC may function after addition of an attractant to cope with increased levels of CheY-P; Belongs to the FliN/MopA/SpaO family.
