Abstract
The purpose of the present invention is to provide an agent for improving intestinal flora which can increase the number of beneficial bacteria such as lactic acid bacteria and Bifidobacterium to improve intestinal flora by using an enzyme. A protease consisting of a polypeptide having an amino acid sequence shown in SEQ ID NO: 1 can increase beneficial bacteria such as lactic acid bacteria and Bifidobacterium in intestines to exert an excellent effect of improving intestinal flora.
Claims2
A method for improving intestinal flora, comprising orally administering a protease comprising at least one of the following polypeptides (1) to (3) to a person who requires improvement of intestinal flora:
- (1) a polypeptide consisting of an amino acid sequence shown in SEQ ID NO:
- 1,
- (2) a polypeptide comprising an amino acid sequence in which one or a few amino acids are substituted, added, inserted, or deleted in the amino acid sequence shown in SEQ ID NO:
- 1, and having a protease activity equivalent to that of a polypeptide consisting of an amino acid sequence shown in SEQ ID NO:
- 1, and
- (3) a polypeptide comprising an amino acid sequence having 80% or more sequence identity to an amino acid sequence shown in SEQ ID NO:
- 1, and having a protease activity equivalent to that of a polypeptide consisting of an amino acid sequence shown in SEQ ID NO:
- 1 wherein the protease increase the number of Bifidobacteria and Lactic add bacteria in intestines of said subject, thereby improves the intestinal flora.
A method of treatment for improving intestinal flora comprising administering a protease comprising at least one of the following polypeptides (1) to (3) to a person who requires improvement of intestinal flora:
- (1) a polypeptide consisting of an amino acid sequence shown in SEQ ID NO:
- 1,
- (2) a polypeptide comprising an amino acid sequence in which one or a few amino acids are substituted, added, inserted, or deleted in the amino acid sequence shown in SEQ ID NO:
- 1, and having a protease activity equivalent to that of a polypeptide consisting of an amino acid sequence shown in SEQ ID NO:
- 1, and
- (3) a polypeptide comprising an amino acid sequence having 80% or more sequence identity to an amino acid sequence shown in SEQ ID NO:
- 1, and having a protease activity equivalent to that of a polypeptide consisting of an amino acid sequence shown in SEQ ID NO:
- 1 wherein the protease increase the number of Bifidobacteria and Lactic add bacteria in intestines of said subject, thereby improves the intestinal flora.
