title: Acid Glycosidase Activities in the Cotyledons of Pisum sativum L.
abstract: The activities of α-mannosidase (EC 3.2.1.24), β-galactosidase (EC 3.2.1.23), and α-galactosidase (EC 3.2.1.22) have been measured in extracts from cotyledons at various stages following germination of pea seeds (Pisum sativum L., cultivars Melbourne Market, Greenfeast, and Telephone). The activities of all three glycosidases are fully accounted for by enzyme synthesis during seed development. The α-mannosidase (isoenzyme 1) from pea cotrledons is inhibited by the indolizidine alkaloid swainsonine with an apparent K(i) of 1.37 \sx 10(-7) M.
