ENZYMIC SYNTHESES OF DOUBLY BRANCHED CYCLOMALTOHEPTAOSES THROUGH THE REVERSE ACTION OF Pseudomonas ISOAMYLASE

Two and three new cyclomaltoheptaose (β-cyclodextrin, cG7) derivatives, respectively, were identified among the products obtained by the action of Pseudomonas isoamylase on maltose and maltotriose, and cG7.They were 6A,6D-di-O-α-maltosyl-cG7 and 6-O-α-(62-O-α-maltosyl)maltosyl-cG7, and 6A,6D-di-O-α-maltotriosyl-cG7, 6-O-α-(63-O-α-maltotriosyl)maltotriosyl-cG7, and 6-O-α-(62-O-α-maltotriosyl)maltotriosyl-cG7.In addition, 61- and 62-O-α-maltosylmaltose were identified as mutual condensation products of maltose.Maltose was the smallest substrate to act as both an acceptor and a donor for the action of Pseudomonas isoamylase.

ISOLATION AND CHARACTERIZATION OF BRANCHED CYCLODEXTRINS

Three branched cyclodextrins (CDs) were isolated by high-performance liquid chromatography (l.c.) from the mother liquors of a large-scale preparation of the unbranched CDs with Bacillus ohbensis cyclomaltodextrin glucanotransferase.Evidence from chromatographic behavior on three l.c. coloumns of different separation modes, fragmentation analysis, 13C-n.m.r. spectroscopy, methylation analysis, and fast-atom bombardment-mass spectroscopy (f.a.b.-m.s.) indicated that these compounds were 6-O-α-D-glucopyranosylcyclomaltohexaose (1), 6-O-α-D-glucopyranosylcyclomaltoheptaose (2), and 6,6'''-di-O-α-D-glucopyranosylcyclomaltoheptaose (3).
