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