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

kinDHistidine kinase phosphorylating Spo0A; Phosphorylates the sporulation-regulatory protein spo0F and, to a minor extent, is responsible for heterogeneous expression of spo0A during logarithmical growth. Also phosphorylates spo0A under biofilm growth conditions. (506 aa)    
Predicted Functional Partners:
spo0F
Two-component response regulator; Key element in the phosphorelay regulating sporulation initiation. Phosphorylation of spo0B during sporulation initiation.
  
 
 0.997
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).
  
 
 0.994
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.
      
 0.890
spo0B
Sporulation initiation phosphotransferase; Key element in the phosphorelay regulating sporulation initiation. Acts on spo0A. Mediates reversible phosphoryl transfer from spo0F to spo0A.
   
  
 0.847
epsA
Modulator of protein tyrosine kinase EpsB; Evidence 2b: Function of strongly homologous gene; regulator.
      
 0.845
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.
      
 0.839
sinI
Antagonist of SinR; Acts as an antagonist to SinR. SinI prevents SinR from binding to its target sequence on the gene for AprE.
   
  
 0.759
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 [...]
      
 0.752
yclJ
Two-component response regulator [YclK]; Could be member of the two-component regulatory system YclK/YclJ.
 
    0.745
phoP
Two-component response regulator; Member of the two-component regulatory system PhoP/PhoR involved in the regulation of alkaline phosphatase genes phoA and phoB and of phosphodiesterase.
