Abstract
An alkaline protease which is suitable for detergent formulations is produced by three strains of a species of Bacillus proteolyticus. 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.
