Cyclodextrin glucanotransferase [1,4-alpha-D-glucan 4-alpha-D-(1,4-alpha-D-glucano)-transferase (cyclizing), EC 2. 4. 1. 19] from an alkalophilic Bacillus species A2-5a had a wider acceptor specificity than that from B. macerans, which was similar to those from B. stearothermophilus and B. circulans. Glucosyl rhamnose produced by the CGTase was identified as glucopyranosyl-alpha-1,4-rhamnopyranose by alpha- and beta-glucosidase treatments, and 1H- and 13C-NMR analyses.
