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

slrRTranscriptional regulator of autolysin genes; Represses sigma(D)-dependent flagellar genes and activate the eps and yqxM operons. Repressor activity is regulated by SlrA. Controls the initiation of biofilm formation. (152 aa)    
Predicted Functional Partners:
sipW
Type I signal peptidase; Required for the cleavage of the signal sequence of TasA and TapA, which are involved in biofilm formation. Belongs to the peptidase S26B family.
 
  
 0.980
sinI
Antagonist of SinR; Acts as an antagonist to SinR. SinI prevents SinR from binding to its target sequence on the gene for AprE.
   
  
 0.979
epsA
Modulator of protein tyrosine kinase EpsB; Evidence 2b: Function of strongly homologous gene; regulator.
  
  
 0.977
tapA
Lipoprotein for biofilm formation; Required for biofilm formation. Required for the proper anchoring and polymerization of TasA amyloid fibers at the cell surface. Is also a minor component of TasA fibers.
   
  
 0.974
slrA
Anti-repressor of SlrR; Required specifically for induction of eps and yqxM operons by antagonizing SinR. Regulates SlrR activity. Controls the initiation of biofilm formation.
      
 0.919
epsE
Bifunctional flagellar clutch and glycosyltransferase; May be involved in the production of the exopolysaccharide (EPS) component of the extracellular matrix during biofilm formation. EPS is responsible for the adhesion of chains of cells into bundles. Required for biofilm maintenance; Belongs to the glycosyltransferase 2 family.
  
  
 0.916
spo0A
Response regulator; 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).
   
  
 0.899
yaaB
Conserved hypothetical protein; Regulates the biosynthesis of the extracellular matrix and the biofilm formation. May act as an enhancer of biofilm gene expression. Acts in parallel to the pathway that governs SinR derepression.
  
   
 0.856
ymdB
Putative hydrolase involved in biofilm formation; Plays a central, regulatory role in the late adaptive responses and affects the levels of many genes. May act via regulation of cAMP levels. Decreases the expression of motility genes and induces genes involved in biofilm formation, by controlling the expression of SlrR. Required for formation of intercellular nanotubes that bridge neighboring cells to allow molecular exchange. Plays a key role in directing the early stages of colony development. In vitro, has a metal-dependent phosphodiesterase activity against 2',3'-cAMP and 2',3'-cGM [...]
      
 0.850
abrB
Transcriptional regulator for transition state genes; Ambiactive repressor and activator of the transcription of genes expressed during the transition state between vegetative growth and the onset of stationary phase and sporulation. It controls the expression of genes spovG and tycA. AbrB binds to the tycA promoter region at two A- and T-rich sites, it may be the sole repressor of tycA transcription; To B.subtilis Abh and SpoVT.
