Abstract
The present invention provides: a protein having a fructosyl amino acid oxidase activity which protein is useful for measurement of a glycosylated protein (particularly, glycosylated hemoglobin); a modified protein thereof; and use of the protein or the modified protein. The protein of the present invention is, for example, a fructosyl valyl histidine oxidase derived from, the fructosyl valyl histidine oxidase having excellent thermal stability and substrate specificity and also having a small Km value to fructosyl valyl histidine. This allows a glycosylated protein measuring reagent to be stored in a long time and measurement accuracy of the glycosylated protein measuring reagent to be improved.
