    摘要： Novel vectors and methods for a single-stranded DNA mediated gene transfer system via transformation, fusion or transduction of Streptomyces, other actinomycetes, and E. coli using a variety of vectors. Phasmid shuttle vectors of the invention are particularly useful as single-stranded vectors that appear to bypass one or more host cell restriction systems, and thus increase the efficiency of gene transfer into highly restrictive host cell systems. New and useful vectors are provided that allow for the cloning of genes both for increasing the yields of known antibiotics and also for producing new antibiotics, antibiotic derivatives, or any other useful gene product, including a variety of mammalian protein products.

    摘要： 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.
