We evaluated the stabilities of kojibiose and sophorose when heated under neutral pH conditions. Kojibiose and sophorose epimerized at the C-2 position of glucose on the reducing end, resulting in the production of 2-O-α-D-glucopyranosyl-D-mannose...
Acrylamide has neurotoxicity, carcinogenicity, and genotoxicity in experimental animals and cellular systems. Fried potato is one of the major intake sources of acrylamide in food, and fried onion was reported to contain up to 100 ng/g level of ac...
We characterized Teth514_1788 and Teth514_1789, belonging to glycoside hydrolase family 130, from Thermoanaerobacter sp. X-514. These two enzymes catalyzed the synthesis of 1,2-β-oligomannan using β-1,2-mannobiose and d-mannose as the optimal acce...

One-pot enzymatic production of nigerose was demonstrated from abundantly available sugar resources, including maltose, cellobiose, sucrose and starch. (i) 319 mM nigerose was generated from 500 mM maltose by the combined actions of maltose phosph...
We discovered a potassium ion-dependent trehalose phosphorylase (Bsel_1207) belonging to glycoside hydrolase family 65 from halophilic Bacillus selenitireducens MLS10. Under high potassium ion concentrations, the recombinant Bsel_1207 produced in ...
Pestalotiopsis spp. strains were isolated from leaves of 17 out of 23 plant species. Some of the Pestalotiopsisspp. isolates showed catechol-xylosylation activity. A catechol-xylosylating enzyme was purified from the culturefiltrate of an isolated...
