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.

ywqEProtein tyrosine-phosphatase; Dephosphorylates the phosphotyrosine-containing proteins YwqD, YwqF and Ssb. (254 aa)    
Predicted Functional Partners:
ptkA
Protein tyrosine kinase; May be involved in the regulation of capsular polysaccharide biosynthesis. Autophosphorylates in vitro. Phosphorylates and activates in vitro two UDP-glucose dehydrogenases, YwqF and TuaD, as well as the DNA-binding proteins Ssb and SsbB; Belongs to the CpsD/CapB family.
  
 0.998
ywqC
Modulator of YwqD protein tyrosine kinase activity; Required for YwqD kinase activity. May bring YwqD and its substrates into contact. Probably involved in the regulation of capsular polysaccharide biosynthesis.
 
 
 0.998
epsB
Protein tyrosine kinase; Evidence 2b: Function of strongly homologous gene; enzyme; Belongs to the CpsD/CapB family.
  
 0.966
ywqF
UDP-glucose dehydrogenase; Catalyzes the conversion of UDP-glucose into UDP-glucuronate, one of the precursors of teichuronic acid. Belongs to the UDP-glucose/GDP-mannose dehydrogenase family.
  
  
 0.953
epsA
Modulator of protein tyrosine kinase EpsB; Evidence 2b: Function of strongly homologous gene; regulator.
 
  
 0.929
yfkJ
Protein-tyrosine-phosphatase; Dephosphorylates the phosphotyrosine-containing proteins. Involved in ethanol stress resistance.
      
 0.909
yabT
Putative serine/threonine-protein kinase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
    
 
 0.862
ywlE
Protein-tyrosine-phosphatase; Catalyzes the specific dephosphorylation of phosphoarginine residues in a large number of proteins. Counteracts the protein arginine kinase McsB in vivo. Can dephosphorylate CtsR-P; thus, can restore the DNA-binding ability of the CtsR repressor by reversing the McsB-mediated phosphorylation. Is the only active pArg phosphatase present in B.subtilis. Exhibits almost no activity against pSer, pThr, or pTyr peptides. Appears to play a role in B.subtilis stress resistance. Protein arginine phosphorylation has a physiologically important role and is involved i [...]
      
 0.836
rsbT
Switch protein/serine-threonine kinase; Provides the crucial link between the upstream module (communication of environmental stress) and the downstream module (integration of the environmental signals with signals of energy stress) that compose the signal transduction pathway controlling the sigma-B factor. Phosphorylates and inactivates its specific antagonist protein RsbS thanks to its serine kinase activity. Upon phosphorylation of RsbS, RsbT is released to stimulate RsbU, a PP2C phosphatase, thereby initiating the signaling cascade that ultimately activates sigma-B. The activity o [...]
    
 
 0.790
epsL
Putative phosphotransferase involved in extracellular matrix synthesis; 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.
