Substrate Specificity ofSaccharomyces logos α-Glucosidase

Partial Purification and Characterization of Acid and Neutralα-Glucosidases from Preclimacteric Banana Pulp Tissues

“…6,9 -) 1) By kinetic parameters (Table IV), the banana AAG was found to be a typical maltase and belongs to the second group, according to the Chiba's classification. That is, it hydrolyzed maltose most rapidly and the highest V maxi Km ratio was obtained by maltose and malto-oligosaccharides (G 3 -G S )' The Km of the AAG for maltose (1 mM) was about 7 times lower than that of the enzyme from Saccharomyces logos, 42) which was also of the second type. Thus the banana AAG is suggested to be resposible for hydrolyzing maltose or mal to-oligo saccharides which would be produced by a-and p-amylolysis or debranching of starch.…”
