    摘要: This invention provides an amadoriase having high reactivity with ±-fructosyl hexapeptide (±F6P) derived from the ²-chain amino terminus of glycated hemoglobin (HbAlc), which enables satisfactory quantification of ±F6P cleaved from HbAlc. A novel amadoriase is derived from the amadoriase of the genus Coniochaeta by substitution of one or more amino acids at positions selected from the group consisting of positions 62, 63, 102, 106, 110, 113, 355, and 419. Such amadoriase enables rapid, simple, accurate, and satisfactory quantification of ±F6P cleaved from HbAlc. With the use of such amadoriase, a method for measurement of HbAlc by an enzymatic method and a kit for measurement of HbAlc that are based on the same principle as used in the conventional standard method and excellent in terms of the relevance with the standard method.

    摘要: Provided is a composition by which glycated hemoglobin can be measured even in the presence of a stronger surfactant than a conventional case. Also provided is a buffer and/or stabilizer which maintains the residual activity of an amadoriase or lowers a reduction of residual activity. The present invention provides a composition for use in measuring glycated hemoglobin containing an amadoriase having substitution of one or more amino acid residues at a position(s) corresponding to an amino acid(s) selected from the group consisting of position 262, position 257, position 249, position 253, position 337, position 340, position 232, position 129, position 132, position 133, position 44, position 256, position 231 and position 81 of an amadoriase derived from the genus Coniochaeta and represented by SEQ ID No: 1 or 3, and having residual activity even in the presence of a surfactant. The present invention also provides a composition and kit for use in measuring glycated hemoglobin, comprising a specific stabilizer and/or a buffer. The present invention can provide an enzyme and a composition for use in measuring glycated hemoglobin, excellent in storage stability even if they are exposed to a surfactant.

    摘要: This invention provides an amadoriase that acts on the ²-chain of hemoglobin A1c (HbA1c) and generates hydrogen peroxide, a method for measurement of HbA1c using such amadoriase, and a reagent kit for measurement of HbAlc using such amadoriase. The method for measurement of HbAlc involves the use of an amadoriase that has specific activity of 0.1 U/mg or greater to ±F6P and oxidizes the HbA1c ²-chain amino terminus so as to generate hydrogen peroxide, and the reagent kit for measurement of HbA1c comprises such amadoriase. The method and the kit for measurement of HbAlc enable quantification of HbAlc to be performed rapidly, simply, and accurately.
