Journal ArticleDOI
Partial Purification and Properties of an Alkaline α-Galactosidase from Mature Leaves of Cucurbita pepo
TL;DR: A fourth molecular from of alpha-galactosidase, designated L(IV) was isolated from leaves of Cucurbita pepo and purified 165-fold, and was active over a narrow pH range with optimal hydrolysis of p-nitrophenyl-alpha-d-Galactoside and stachyose at pH 7.5.
Journal ArticleDOI
Alkaline α-galactosidase activity and galactose metabolism in the family Cucurbitaceae
TL;DR: It is suggested that in cucurbits immature leaf tissue rapidly metabolizes stachyose through increased levels of alkaline α-galactosidase and other enzymes associated with galactose utilisation.
Journal ArticleDOI
Stachyose synthesis in leaves of Cucurbita pepo
TL;DR: It is proposed that the synthesis of stachyose in mature leaves of C. pepo proceeds via this galactosyltransferase and not via α-galactosidase, and was optimally active at pH 6.9 and stable for at least a month at 4° in the presence of 20 mM 2-mercaptoethanol.
