title: Secretory production of recombinant proteins by Streptomyces.
abstract: Bacterial systems are widely applied as production platforms for proteins of biopharmaceutical or therapeutic interest and industrial enzymes. Among these prokaryotic systems, streptomycetes are attractive host cells because several strains of these Gram-positive bacteria have a high innate secretion capacity and extensive knowledge on their fermentation is available. A survey of the literature and our own experience suggests that several proteins are secreted to commercially acceptable levels. However, many heterologous proteins, most often of eukaryotic origin, are currently only poorly secreted by this host, indicating the need for further optimization of Streptomyces as a production host. In this review, the considerable efforts and strategies made in recent years aimed at improving streptomycetes as a host for the production of recombinant proteins will be discussed.
