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

natKTwo-component sensor histidine kinase [NatR]; Member of the two-component regulatory system NatK/NatR that positively regulates the expression of the natAB operon. Potentially phosphorylates NatR. (318 aa)    
Predicted Functional Partners:
natR
Two-component response regulator [NatK]; Member of the two-component regulatory system NatK/NatR that positively regulates the expression of the natAB operon. Acts by binding directly to the promoter of natAB.
 
 
 0.999
yufM
Two-component response regulator [YufL]; Member of a two-component regulatory system MalK/MalR. Activates transcription of maeA, maeN and yflS in presence of malate by binding to their promoter region.
 
 
 0.657
dctR
Two-component response regulator; Member of the two-component regulatory system DctS/DctR. Essential for expression of dctP.
 
 
 0.629
citT
Two-component response regulator; Member of the two-component regulatory system CitT/CitS. Regulates the expression of the citM-yflN operon. Phosphorylated CitT binds to the citM promoter to activate the transcription of the citM- yflN operon.
 
 
 0.619
natA
Na+ ABC efflux transporter (ATP-binding protein); Part of an ABC transporter that catalyzes ATP-dependent electrogenic sodium extrusion; Belongs to the ABC transporter superfamily.
 
    0.588
natB
Na+ ABC efflux transporter (permease); Part of an ABC transporter that catalyzes ATP-dependent electrogenic sodium extrusion.
  
    0.540
yufL
Two-component sensor histidine kinase [YufM]; Member of a two-component regulatory system MalK/MalR. Involved in the activation of maeA, maeN and yflS in presence of malate. Probably activates MalR by phosphorylation.
  
    0.477
ytcC
Putative glucosyltransferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the glycosyltransferase group 1 family. Glycosyltransferase 4 subfamily.
  
     0.470
cotSA
Spore coat protein; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type cp: cell process; Belongs to the glycosyltransferase group 1 family. Glycosyltransferase 4 subfamily.
  
     0.424
dctS
Two-component sensor histidine kinase; Member of the two-component regulatory system DctS/DctR. Probably activates DctR by phosphorylation (By similarity). Essential for expression of dctP.
  
    0.417
