    摘要: The present invention provides methods and compositions for the production of mature proteases in bacterial host cells. The compositions include modified polynucleotides that encode modified proteases, which have at least one mutation in the pro region; the modified serine proteases encoded by the modified polynucleotides; expression cassettes, DNA constructs, and vectors comprising the modified polynucleotides that encode the modified proteases; and the bacterial host cells transformed with the vectors of the invention. The methods include methods for enhancing the production of mature proteases in bacterial host cells e.g. Bacillus sp. host cells. The produced proteases find use in the industrial production of enzymes, suitable for use in various industries, including but not limited to the cleaning, animal feed and textile processing industry.
