Abstract
Methods and compositions are provided for endopeptidase production, enhanced efficiencies of processing in vivo and in vitro to provide for process polypeptides, and purified enzyme for in vitro processing of polypeptides. The endopeptidase is specific for dibasic amino acid sites, cleaving at the C-side of the dipeptide. The S. cerevisiae strain pYBCA-5 (truncated KEX2) was deposited at the A.T.C.C. on June 21, 1984 and given Accession No. 20717.
