摘要:
Cyclodextrin glycosyltransferase (CGTase) is an enzyme able to convert starch and other substrates into cyclodextrins (CDs). An alpha-cyclodextrin glycosyltransferase (alpha-CGTase) from the Bacillus sp. Y112, isolated from the Yellow Sea in China has been purified by ethanol precipitation, gel filtration and anion-exchange chromatography with a yield of 57.5%. The purified enzyme was a monomer and its molecular weight was estimated to be 90 kDa. The enzyme was stable over a pH range of 7.0 to 9 ...More
