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

cynSCyanate aminohydrolase; Catalyzes the reaction of cyanate with bicarbonate to produce ammonia and carbon dioxide. (156 aa)    
Predicted Functional Partners:
cynT
Carbonic anhydrase; Reversible hydration of carbon dioxide. Carbon dioxide formed in the bicarbonate-dependent decomposition of cyanate by cyanase (CynS) diffuses out of the cell faster than it would be hydrated to bicarbonate, so the apparent function of this enzyme is to catalyze the hydration of carbon dioxide and thus prevent depletion of cellular bicarbonate.
 
 
 0.998
cynX
Putative cyanate transporter; This protein is part of an active transport system that transports exogenous cyanate into E.coli cells; Belongs to the major facilitator superfamily. Cyanate porter (TC 2.A.1.17) family.
  
  
 0.969
can
Putative carbonic anhdrase; Belongs to the beta-class carbonic anhydrase family.
    
 0.964
yahI
Carbamate kinase-like protein; Putative kinase; Protein involved in arginine biosynthetic process and pyrimidine nucleotide biosynthetic process; Belongs to the carbamate kinase family.
   
 
  0.902
ybcF
Putative carbamate kinase; Protein involved in arginine biosynthetic process and pyrimidine nucleotide biosynthetic process.
   
 
  0.900
yqeA
Putative kinase; Belongs to the carbamate kinase family.
     
  0.900
cynR
Transcriptional activator of cyn operon; Positively regulates the cynTSX operon, and negatively regulates its own transcription. Binds specifically to the cynR-cynTSX intergenic region.
 
  
 0.765
cmtA
Putative mannitol-specific PTS IIB and IIC components; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II CmtAB PTS system is involved in D-mannitol transport.
      
 0.504
ycgM
Putative isomerase; Belongs to the FAH family.
 
      0.474
nirC
Nitrite transporter; Catalyzes nitrite uptake and nitrite export across the cytoplasmic membrane. Is up to 10-fold more active than NarK or NarU in nitrite uptake for subsequent reduction in the cytoplasm by the NirB/NirD nitrite reductase; Belongs to the FNT transporter (TC 2.A.44) family.
