Expression vectors, DNA fragments, peptides, hosts, and process for production of proteins.

摘要

This invention provides an expression vector which comprises a structural gene coding for cardionatrin and/or cardiodilatin or a least a portion of a cardionatrin-like and/or cardiodilatin-like peptide. Also provided in the invention is a DNA fragment which comprises a base sequence coding for cardionatrin and/or cardiodilatin or a cardionatrin-like and/or cardiodilatin-like peptide. Further, cardiodilatin or a cardiodilatin-like peptide is provided according to the present invention. Also, this invention relates to a transformant for use in the production of said peptide as well as to a process for production thereof.
