Abstract
Gene fusions of DNA sequences encoding protein A from Staphylococcus aureus (spa) with expression elements from an alpha-amylase gene from Bacillus amyloliquefaciens (amyEBamP) directed the synthesis and efficient secretion of protein A in Bacillus subtilis. The fusions were established on multicopy pUB110-based plasmid vectors, in contrast to the intact spa gene, which could not be stably established on plasmids in B. subtilis. Some of the resulting B. subtilis strains secreted protein A at levels in excess of 1 g/liter, demonstrating that a foreign protein encoded by an engineered gene can be secreted by B. subtilis at levels comparable to endogenous exoproteins.
