Abstract
The present invention provides a protein having pentosidine oxidase activity, a method for measuring pentosidine comprising: contacting the protein with a specimen; and detecting a change caused by the contact, and the like.
Claims8
A method for measuring pentosidine, comprising:
- contacting a protein with a specimen, wherein the protein is selected from the group consisting of:
- (a) a protein consisting of an amino acid sequence as set forth in SEQ ID NO:
- 2 or 4;
- (b) a protein encoded by a gene consisting of a nucleotide sequence as set forth in SEQ ID NO:
- 1, 3, 5 or 6;
- (c) a protein comprising at least 90% sequence identity to SEQ ID NO:
- 2 or 4;
- and
- (d) a protein encoded by a gene comprising at least 90% sequence identity to SEQ ID NO:
- 1, 3, 5 or 6;
- and
- detecting a change caused by the contact.
