additional information | the starch-binding domains of Bacillus stearothermophilus ET1 CGTase (E and DE) are introduced into the C-terminus of TAalphaGT to enhance the starch utilizing activity. The chimeric enzymes, TAalphaGT-E and TAalphaGT-DE, show no difference in temperature optimum, transglycosylation activity, and amylolytic degradation pattern compared to TAalphaGT wild-type. However, TAalphaGT-DE exhibits the highest molar specific activity toward amylose. TAalphaGT-DE modifies amylopectin molecules by its disproportionating activities to produce modified amylopectin clusters (MW 1000001000000) and produces cyclo-amyloses with DP of 19 through 35 from amylose molecules | Thermus aquaticus |
