By the partial purification of Arthrobacter nicotinovorus D-97 endocellular enzymes and the results of enzymatic reaction of enzymes of partition collection, it was found that enzymes related to trehalose synthesis were consisted of Trehalose-forming Enzyme and Trehalose-releasing Enzyme . Trehalose-forming Enzyme could convert maltooligosaccharides into non-reducing maltooligosyl trehalose by intramolecular transglycosylation, and Trehalose-releasing Enzyme could hydrolyze α-1, 4 linkage between the trehalose residue and the maltooligosaccharide residue to release trehalose and maltooligosaccharides with two glucose monomer lesser.
