SYSTEMATIC NAME
IUBMB Comments
(1->4)-alpha-D-glucan:(1->4)-alpha-D-glucan 4-alpha-D-[(1->4)-alpha-D-glucano]-transferase (cyclizing)
Cyclomaltodextrins (Schardinger dextrins) of various sizes (6,7,8, etc. glucose units) are formed reversibly from starch and similar substrates. Will also disproportionate linear maltodextrins without cyclizing (cf. EC 2.4.1.25, 4-alpha-glucanotransferase).

the reactions are optimized by using different ratios of the D-glucopyranosides to cyclomaltohexaose. The lower ratios of 0.5-1.0 give a wide range of sizes from d.p. 2-17 and higher. As the molar ratio is increased from 1.0 to 3.0, the larger sizes, d.p. 9–17, decrease, and the small and intermediate sizes, d.p. 2–8, increase. As the molar ratios are increased further from 3.0 to 5.0, the large sizes completely disappear, the intermediate sizes, d.p. 4–8, decrease, and the small sizes, d.p. 2 and 3 become predominant

the cyclodextrin product specificity can be changed into linear product specificity, by introducing a five-residue insertion mutation at the donor substrate binding subsites. The CGTase mutants remain clearly different from the maltogenic alpha-amylase, as they have much lower hydrolytic activities, they form linear products of variable sizes and they retain a low cyclodextrin forming activity, whereas maltogenic alpha-amylases produce primarily maltose. The five-residue insertion, concomitantly, strongly enhances the exo-specificity of CGTase
