Abstract

Fructosyl amino acid oxidase is provided, which has an amino acid sequence as shown in SEQID. No. 1 or fructosyl amino acid oxidase having a homology of more than 80% with this amino acid sequence, on a corresponding site of an amino acid selected from following (a) to (f), having one or more amino acid residues conducting a substitution, obtained fructosyl amino acid oxidase having a higher thermostability: (a) 59-site glutamic acid, (b) 98-site glutamic acid, (c) 225-site glycine, (d) 277-site lysine, (e) 285-site glutamic acid, and (f) 355-site aspartic acid. The method for preparing the above oxidase and the test kit containing the enzyme for determining glycated albumin are also provided.
