METHOD FOR MANUFACTURING KETOSE USING NOVEL KETOSE-3-EPIMERASE

This invention provides a method for producing allulose using an allulose-producing enzyme having high pH stability in a low-pH region. The method comprises a step of allowing a polypeptide consisting of the amino acid sequence shown in SEQ ID NO: 6 or a polypeptide consisting of a sequence having 9...

Beschreibung
Zusammenfassung:	This invention provides a method for producing allulose using an allulose-producing enzyme having high pH stability in a low-pH region. The method comprises a step of allowing a polypeptide consisting of the amino acid sequence shown in SEQ ID NO: 6 or a polypeptide consisting of a sequence having 90% or higher identity to the amino acid sequence shown in SEQ ID NO: 6 and capable of producing allulose to react with fructose under acidic conditions in which pH is less than 6.
