Abstract
A method for expressing a functional polypeptide in Streptomyces comprises transforming a Streptomyces host cell with a recombinant DNA expression vector and then culturing the transformed cell under conditions suitable for cell growth. The recombinant DNA expression vector comprises the veg or any other homologous Bacillus promoter, a naturally occurring or modified ribosome binding site-containing DNA sequence and a gene that codes for a functional polypeptide such as human pre-proinsulin. The method is specifically exemplified by use of expression plasmids pOW529, pOW539 and transformants, Streptomyces ambofaciens/pOW529 and Streptomyces ambofaciens/pOW539. The method is broadly applicable and is particularly useful in economically important Streptomyces taxa.
