Characterization of an Alkaline GH49 Dextranase from Marine Bacterium <i>Arthrobacter</i> <i>oxydans</i> KQ11 and Its Application in the Preparation of Isomalto-Oligosaccharide

A GH49 dextranase gene DexKQ was cloned from marine bacteria <i>Arthrobacter oxydans</i> KQ11. It was recombinantly expressed using an <i>Escherichia coli</i> system. Recombinant DexKQ dextranase of 66 kDa exhibited the highest catalytic activity at pH 9.0 and 55 &#176;C....
