Isolation and Characterization of Three α-Glucosidases from the Japanese Quail1

Abstract
We have defined one type of acid α -glucosidase and two types of neutral α -gluco-sidases from quail skeletal muscle on the basis of differences in the elution patterns on a DEAE-cellulose column. The appearance of the two neutral a-glucosidase isoenzymes was age-dependent. A decrease in acid α -glucosidase activity was demonstrated in Japanese quails with glycogenosis type II. The characteristics of these three α -glucosidase isoenzymes are described.
