摘要: The present invention has a purpose of providing a technique for increasing the heat resistance of a ²-galactosidase. According to the present invention, in a reference ²-galactosidase amino acid sequence which shows a 90% or more identity to the amino acid sequence of SEQ ID NO: 4, proline is substituted for one or more amino acids selected from the group consisting of the following amino acids: (1) an amino acid corresponding to lysine at position 166 of the amino acid sequence of SEQ ID NO: 4, (2) an amino acid corresponding to glycine at position 307 of the amino acid sequence of SEQ ID NO: 4, and (3) an amino acid corresponding to alanine at position 833 of the amino acid sequence of SEQ ID NO: 4.

摘要: The present invention addresses a problem of providing a lipase derived from a microorganism that is specific for short-chain to medium-chain fatty acids. A modified lipase is obtained by making a substitution in the amino acid sequence of a Candida cylindracea derived lipase, wherein the substitution is (1) a substitution of asparagine for an amino acid corresponding to the amino acid at position 428 in the amino acid sequence set forth in SEQ ID NO: 1; or (2) a substitution of phenylalanine, methionine, or isoleucine for an amino acid corresponding to the amino acid at position 429 in the amino acid sequence set forth in SEQ ID NO: 1.
