title: Identification, mapping, and cloning of the gene encoding cyanase in Escherichia coli K-12.
abstract: The gene in Escherichia coli for cyanase, designated cynS, was localized to a BglII restriction site approximately 1.7 kilobases from the lacA end of the lac operon. The gene was cloned into the pUC13 vector. Maxicell analysis of plasmid-encoded proteins confirmed that the BglII site is in the region encoding the structural gene for cyanase. Cyanase-deficient strains had increased sensitivity to cyanate and were not able to use cyanate as a nitrogen source.
