摘要：

Potato tuber α-glucosidase has an isoelectric point of 4.7 and an apparent MW of 120 000. The enzyme has a neutral pH optimum (pH 6.5-7.0) and a Km of 0.21 mM for p-nitrophenol-α-D-glucoside at pH 6.8 and 30°. Maltose and higher maltosaccharides are also substrates. The enzyme exhibits transglucosidase activity. © 1978.
