Host cells and methods of producing disulfide bond containing proteins

摘要

The invention provides for genetically modified Bacillus host cells having decreased cytoplasmic reductase activity, such as decreased TrxA activity, and a nucleic acid encoding a heterologous Staphylococcal oxidase. The invention also provides for methods of producing di-sulfide bond containing proteins using the host cells of the invention and methods of improving protein folding using the host cell of the invention.
