sucrose | transglucosylation activity is significantly higher than the hydrolytic activity. The main product generated from sucrose is structurally determined to be alpha-(1,4)-glucan. A small amount of glucose is produced by hydrolysis, and sucrose isomers including turanose and trehalulose are generated as minor products. The ratio of hydrolytic, polymerization, and isomerization reactions is calculated to be 5.8:84.0:10.2. The enzyme favors production of long-chain insoluble alpha-glucan at lower temperature | Cellulomonas carbonis | alpha-glucan + turanose + trehalulose | - |
