RX MEDLINE=96187580; PubMed=8611744; RA Nakada T., Maruta K., Tsusaki K., Kubota M., Chaen H., Sugimoto T., RA Kurimoto M., Tsujisaka Y.; RT "Purification and properties of a novel enzyme, maltooligosyl RT trehalose synthase, from Arthrobacter sp. Q36."; RL Biosci. Biotechnol. Biochem. 59:2210-2214(1995). CC -!- FUNCTION: Catalyzes the conversion of maltooligosaccharide into CC the non-reducing saccharide, maltooligosyl trehalose (alpha- CC maltooligosyl alpha-D-glucoside) by intramolecular CC transglycosylation. CC -!- CATALYTIC ACTIVITY: 4-((1->4)-alpha-D-glucosyl)(n-1)-D-glucose = CC 1-alpha-D-((1->4)-alpha-D-glucosyl)(n-1)-alpha-D-glucopyranoside. CC -!- SUBUNIT: Monomer. CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 13 family.
