Abstract:
1. An isolated nucleic acid encoding an alkaline protease having an amino acid sequence which is at least 90% homologous to an amino acid sequence of SEQ ID NO: 1, wherein said alkaline protease has alkaline protease activity, and said alkaline protease has the following physicochemical properties: (i) Acting pH range acting over a wide pH range of 4-13 and exhibiting, at a pH of 6-12, 80% or more the activity at the optimum pH; (ii) Stable pH range being stable over a pH range of 6-11 when treated at 40° C. for 30 minutes; (iii) Isoelectric point of approximately 8.9-9.1; and (iv) Effect of a fatty acid casein-degrading activity not being inhibited by oleic acid.
