    摘要: The present invention provides methods and compositions comprising at least one neutral metalloprotease enzyme in the relative absence of serine protease enzyme contaminants. In some embodiments, the neutral metalloprotease finds use in cleaning and other applications. In some particularly preferred embodiments, the present invention provides methods and composi-tions comprising Bacillus strains engineered to be deficient in multiple serine proteases, and their use in production of recombinant neutral metalloprotease(s).

    摘要: The present invention relates to cells that have been genetically manipulated to have an altered capacity to produce expressed proteins. In particular, the present invention relates to Gram-positive microorganisms having exogenous nucleic acid sequences introduced therein and methods for producing proteins in such host cells, such as members of the genus Bacillus. More specifically, the present invention relates to the expression, production and secretion of a polypeptide of interest and to cells that have been genetically manipulated to have an altered capacity to produce expressed proteins. In particular, the present invention provides for the enhanced expression of a selected polypeptide by a microorganism.
