Fructosyl amino acid oxidase, process for producing the same, and method of assaying amadori compounds using the enzyme

摘要

The present invention relates to a fructosyl amino acid oxidase that is obtainable from a culture of a strain of the genus Aspergillus. This strain grows in a selective medium containing at least either of fructosyl lysine and fructosyl-N.sup.&agr; -Z-lysine and is capable of producing a fructosyl amino acid oxidase.
