Publication number: 20150344925Abstract: There are provided a highly safe epimerase usable in food industry, and a method for producing a ketose. The epimerase is a ketose 3-epimerase obtainable from a microorganism of the genus Arthrobacter, and having the amino acid sequence represented by SEQ ID NO: 1 of the Sequence Listing, and (1) substrate specificity whereby a D- or L-ketose is epimerized at position 3 to produce a corresponding D- or L-ketose, and (2) the highest substrate specificity for D-fructose and D-psicose among D- and L-ketoses. The ketose 3-epimerase is also represented by SEQ ID NO: 3 or SEQ ID NO: 4 of the Sequence Listing, and epimerizes a D- or L-ketose at position 3 to produce a corresponding D- or L-ketose.Type: ApplicationFiled: December 26, 2013Publication date: December 3, 2015Applicants: MATSUTANI CHEMICAL INDUSTRY CO., LTD., IZUMORING CO., LTD.Inventors: Ken Izumori, Pushpa Kiran Gullapalli, Tomoya Shintani, Ryo Kikkawa

Patent number: 9109266Abstract: Problems Development of a process of producing inexpensive and safe hexose and compositions of the same. Means for Resolution A process of producing a sugar composition comprising a definite amount of an target hexose, comprising treating a starting liquid sugar material comprising a starting sugar material hexose or a mixture comprising hexose in a system in the presence of one or more types selected from the group consisting of basic ion exchange resins, alkalis and calcium salts to initiate an isomerization reaction as an equilibrium reaction to transform the starting sugar material hexose to the target hexose to prepare a sugar mixture comprising a definite amount of the target hexose and having a sugar constitution different from that of the starting sugar material, and hexose compositions containing D-allose and D-psicose and the use of the hexose compositions.Type: GrantFiled: March 26, 2010Date of Patent: August 18, 2015Assignees: MATSUTANI CHEMICAL INDUSTRY CO., LTD., IZUMORING CO., LTD., NATIONAL UNIVERSITY CORPORATION KAGAWA UNIVERSITYInventors: Satoshi Takamine, Tetsuo Iida, Kazuhiro Okuma, Tsuyoshi Shimonishi, Ken Izumori, Tatsuhiro Matsuo
