    The product of the cynT gene of the cyn operon in Escherichia coli has been identified as a carbonic anhydrase. The cyn operon also includes the gene cynS, encoding the enzyme cyanase...

    ..The 26-kDa protein was identified as a cyanate permease that transports exogenous cyanate by active transport. E. coli was shown to contain a cyanate transport system that is energy dependent and saturable by cyanate. ..
