A synthetic DNA sequence and its genetic equivalents are disclosed which sequences are capable, when used in a recombinant DNA method, of directing production of a serine protease inibitor protein. Recombinant DNA methods for the production of serine protease inhibitor proteins are also disclosed. These methods incorporate either the synthetic DNA sequence of the present invention or natural DNA sequences isolated from human cDNA or genomic libraries.

Recombinant methods for production of serine protease inhibitors and DNA sequences

A synthetic DNA sequence and its genetic equivalents are disclosed which sequences are capable, when used in a recombinant DNA method, of directing production of a serine protease inibitor protein. Recombinant DNA methods for the production of serine protease inhibitor proteins are also disclosed. These methods incorporate either the synthetic DNA sequence of the present invention or natural DNA sequences isolated from human cDNA or genomic libraries. In addition, a single polypeptide chain protein is disclosed which is capable of inhibiting chymotrypsin and elastase but not trypsin. In one embodiment, this protein is a shortened from (single domain) of the protein produced by the method described herein.
