Isolation and sequence analysis of the gene (cpdB) encoding periplasmic 2',3'-cyclic phosphodiesterase.

The cpdB gene encodes a periplasmic 2',3'-cyclic phosphodiesterase (3'-nucleotidase). This enzyme has been purified previously and the gene is located at 96 min on the Escherichia coli chromosome. In this study the cpdB gene was cloned from ClaI-cleaved DNA, and the gene product was identified. DNA blotting experiments showed that the recombinant plasmid contains a deletion with respect to the expected genomic fragment of approximately 4 kilobases, which extends into the vector. Furthermore, the gene was absent from three other recombinant libraries. Together, these findings suggest the presence in the genome of an adjacent gene whose product is lethal when it is present on a multicopy plasmid. The nucleotide sequence of the cpdB gene was also determined. The 5' and 3' untranslated sequences contain characteristic sequences that are involved in the initiation and termination of transcription, including two possible promoters, one of which may contain two overlapping -10 sequences. A strong Shine-Dalgarno sequence is followed by an open reading frame which corresponds to a protein having a molecular weight of 70,954. The first 19 amino acid residues have the characteristics of a signal peptide. The 3' untranslated sequence contains two putative rho-independent transcription terminators having low thermodynamic stability. << Less
