A modified secretion system to increase expression of polypeptides in bacteria

摘要

The present invention provides methods of altering the production of desired polypeptides in a host cell. In particular, the present invention provides polynucleotides encoding SecG proteins capable of facilitating the secretion of desired proteases by a bacterial host cell, such as Bacillus species, as well as expression vectors and a host cell containing the polynucleotides.
