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

Score
kinETwo-component sensor histidine kinase; Phosphorylates the sporulation-regulatory protein spo0A under biofilm growth conditions. Also able to weakly phosphorylate spo0F. (738 aa)    
Predicted Functional Partners:
spo0F
Two-component response regulator; Key element in the phosphorelay regulating sporulation initiation. Phosphorylation of spo0B during sporulation initiation.
  
 
 0.998
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).
  
 
 0.992
spo0B
Sporulation initiation phosphotransferase; Key element in the phosphorelay regulating sporulation initiation. Acts on spo0A. Mediates reversible phosphoryl transfer from spo0F to spo0A.
  
   
 0.928
ogt
O6-alkylguanine DNA alkyltransferase; Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) and O4-methylthymine (O4-MeT) in DNA. Repairs the methylated nucleobase in DNA by stoichiometrically transferring the methyl group to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated.
  
    0.830
spo0E
Negative regulatory phosphatase acting on Spo0A-P (sporulation); Aspartyl-phosphate phosphatase which specifically dephosphorylates the sporulation transcription factor Spo0A-P and negatively regulates the sporulation initiation pathway in order to control the proper timing of sporulation. Belongs to the spo0E family.
     
 0.761
kinB
Two-component sensor histidine kinase; Phosphorylates the sporulation-regulatory proteins spo0A and spo0F. Spo0F is required for the KinB activity.
  
  
0.699
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.
      
 0.680
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.
 
     0.663
kinD
Histidine 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.
  
  
0.641
resD
Two-component response regulator; Member of the two-component regulatory system ResD/ResE. Required for the expression of resA, ctaA, qcrABC and fnr; activation role in global regulation of aerobic and anaerobic respiration.
