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

abrBTranscriptional 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. (96 aa)    
Predicted Functional Partners:
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).

sinR
Master regulator of biofilm formation; Negative as well as positive regulator of alternate developmental processes that are induced at the end of vegetative growth in response to nutrient depletion. Binds to the alkaline protease (aprE) gene at two sites. Also acts as a repressor of the key sporulation gene spo0A. Negatively regulates transcription of the eps operon, which is responsible for the biosynthesis of an exopolysaccharide involved in biofilm formation; therefore it could govern the transition between a state in which bacteria swim or swarm and a state in which bacteria assemb [...]

codY
Transcriptional regulator, GTP and BCAA-dependent; DNA-binding protein that represses the expression of many genes that are induced as cells make the transition from rapid exponential growth to stationary phase and sporulation. It is a GTP- binding protein that senses the intracellular GTP concentration as an indicator of nutritional limitations. At low GTP concentration it no longer binds GTP and stop to act as a transcriptional repressor.
  
   
 0.941
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.
  
   
 0.939
comK
Competence transcription factor (CTF); A master regulator required for the expression of late competence genes including comC, comE, comG and the bdbDC operon. Receives signals from SrfA, and possibly other regulatory COM genes, and transduces these signals to the late COM genes. Represses transcription of rok. May repress expression of a few genes.
  
   
 0.922
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.
      
 0.912
sinI
Antagonist of SinR; Acts as an antagonist to SinR. SinI prevents SinR from binding to its target sequence on the gene for AprE.
      
 0.893
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.
      
 0.890
epsA
Modulator of protein tyrosine kinase EpsB; Evidence 2b: Function of strongly homologous gene; regulator.
      
 0.848
spo0F
Two-component response regulator; Key element in the phosphorelay regulating sporulation initiation. Phosphorylation of spo0B during sporulation initiation.
