Reac. |
maltodextrin + glycosyl acceptor |
displays unusually high amylolytic activity in relation to the cyclization activity. Disproportionation activity of the CGTase is optimal with maltose as the acceptor substrate. Cyclization reaction and beta-cyclodextrin formation are significantly promoted in the presence of CaCl2. The salt allows the cyclization reaction to be performed at higher temperature |
Salipaludibacillus agaradhaerens |
beta-cyclodextrin + alpha-cyclodextrin + gamma-cyclodextrin |
the product of cyclization reaction is predominantly beta-cyclodextrin along with alpha-cyclodextrin as a minor product. The CDs profile is influenced by the reaction conditions. At pH 10, alpha-cyclodextrin is replaced by gamma-cyclodextrin formation |
