Abstract
This invention provides an amadoriase having high substrate specificity to fructosyl valyl histidine. Such amadoriase comprises substitution of one or more amino acid residues at positions corresponding to amino acids selected from the group consisting of position 98, position 259, position 154, position 125, position 261, position 263, position 106, position 103, position 355, position 96, position 66, position 67, position 70, position 100, position 110, position 113, position 114, and position 156 in the amadoriase derived from the genus. This invention enables accurate measurement of α-fructosyl valyl histidine derived from the β-chain amino terminus in glycated hemoglobin in the presence of ε-fructosyl lysine.
