ABSTRACT:
Three strains of a species of Bacillus proteolyticus are provided. This bacterium produces an alkaline protease which is suitable for detergent formulations. The alkaline protease has the amino acid terminal sequence of Seq. ID NO.: 1 as follows: Ala-Gln-Ser-Val-Pro-Trp-Gly-Ile-Ser-Arg-Val-Gln-Ala-Pro-Ala-Ala-His-Asn-Ar g-Gly-. In addition, the alkaline protease has a molecular weight of 28 kdaltons, an isoelectric point from 10-11.5, an optimum pH for proteolytic activity at a pH in the range of 8.5 and 11.5, and retains at least 70% of its original activity after being held at a pH of 8.0 at a temperature of 43.degree. C. for a period of 11 days.
