Patent number: 8067204Abstract: A method for producing a chondroitin sugar chain comprises reacting a glucuronic acid donor, an N-acetyl galactosamine donor, a sugar receptor and a bacterial cell enzyme which synthesizes chondroitin in the presence of a surfactant. The surfactant is selected from polyoxyethylene octadecyl amine, n-decanoyl-N-methylglucamide, sodium cholate, n-octyl-?-D-thioglucopyranoside, n-nonyl-?-D-thiomaltopyranoside, sucrose monocholate, sucrose monocaprate, and sucrose monolaurate. The chondroitin sugar chain has all the following properties: a weight average molecular weight: 50,000 or more when measured by gel filtration chromatography; it is completely degraded to disaccharides with chondroitinase ABC; and when the sugar chain is decomposed with chondroitinase ABC and the decomposed products are subjected to a disaccharide analysis, substantially all of them correspond to an unsaturated disaccharide unit of chondroitin.Type: GrantFiled: December 14, 2006Date of Patent: November 29, 2011Assignee: Seikagaku CorporationInventors: Nobuo Sugiura, Satoshi Shimokata, Koji Kimata
