  • Publication number: 20240401017
    Abstract: The present invention provides methods and compositions comprising at least one neutral metalloprotease enzyme that has improved storage stability. In some embodiments, the neutral metalloprotease finds use in cleaning and other applications. In some particularly preferred embodiments, the present invention provides methods and compositions comprising neutral metalloprotease(s) obtained from Bacillus sp. In some more particularly preferred embodiments, the neutral metalloprotease is obtained from B. amyloliquefaciens. In still further preferred embodiments, the neutral metalloprotease is a variant of the B. amyloliquefaciens neutral metalloprotease. In yet additional embodiments, the neutral metalloprotease is a homolog of the the B. amyloliquefaciens neutral metalloprotease. The present invention finds particular use in applications including, but not limited to cleaning, bleaching and disinfecting.
