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.

First claim

We claim:

1. An isolated Bacillus neutral metalloprotease variant comprising multiple mutations selected from F130L/M138L, wherein said variant has at least 95% sequence identity to SEQ ID No: 18, wherein the variant has improved storage stability compared to the parental polypeptide.

2. The isolated neutral metalloprotease variant of claim 1 ,
wherein said variant further comprises at least one substitution at a position selected from at least one position equivalent to positions 1, 3, 4, 5, 6, 11, 12, 13, 14, 16, 21, 23, 24, 25, 31, 32, 33, 35, 36, 38, 44, 45, 46, 47, 48, 49, 50, 51, 54, 55, 58, 59, 60, 61, 62, 63, 65, 66, 69, 70, 76, 85, 86, 87, 88, 90, 91, 92, 96, 97, 98, 99, 100, 102, 109, 110, 111, 112, 113, 115, 117, 119, 127, 128, 129, 132, 135, 136, 137, 139, 140, 146, 148, 151, 152, 153, 154, 155, 157, 158, 159, 161, 162, 169, 173, 178, 179, 180, 181, 183, 184, 186, 190, 191, 192, 196, 198, 199, 200, 202, 203, 204, 205, 210, 211, 214, 215, 216, 217, 218, 219, 220, 221, 222, 223, 224, 228, 229, 237, 239, 240, 243, 244, 245, 248, 252, 253, 260, 261, 263, 264, 265, 267, 269, 270, 273, 277, 280, 282, 283, 284, 285, 286, 288, 289, 290, 292, 293, 296, 297, and 299, of a neutral metalloprotease comprising the amino acid sequence set forth in SEQ ID NO:18.
