3-KETOSE 3-EPIMERASE PRODUCED BY ARTHROBACTER GLOBIFORMIS

摘要

Challenge: Providing a method for producing highly stable epimerase and ketose for use in the food industry. Solution: ketose 3-epimerase obtained from microorganisms belonging to the genus Arthrobacter and having the amino acid sequence represented by SEQ ID NO: 1 in the sequence list and the following substrate specificity: (1) D- or L -Epimerize position 3 of ketose to generate the corresponding D- or L-ketose. (2) Among D- or L-ketose, substrate specificity for D-fructose and D-psicose is highest. And ketose 3-epimerase to generate a corresponding D- or L-ketose by epimerizing the position 3 of D- or L-ketose represented by SEQ ID NO: 3 or SEQ ID NO: 4 in the sequence list.
