The Appearance of New Active Forms of Trypsin Inhibitor in Germinating Mung Bean (Vigna radiata) Seeds.
Ungerminated seeds of mung bean contain a single major species (F) of trypsin inhibitor with five minor species (A-E) separable on diethylaminoethyl-cellulose. During germination the level of trypsin inhibitory activity decreases from 1.8 units/grams dry weight in ungerminated cotyledons to 1.2 units/grams in cotyledons from seeds germinated 5 days. This decrease is accompanied by major changes...

متن کاملThe induction of enzyme activity in the endosperm of germinating castor-bean seeds.
Endosperm extracts were prepared at various times during germination from intact castor-bean seeds and from seeds from which the embryos had been removed. The sterilized seeds were incubated either on solid water agar or on agar containing 0.3 mM-gibberellic acid. 2. Isocitrate lyase and 3-hydroxyacyl-CoA dehydrogenase had very low activities in the mature seeds, but increased 44-fold and 27-fo...
متن کاملProteases of germinating winged-bean (Psophocarpus tetragonolobus) seeds: purification and characterization of an acidic protease.
Two major classes of protease are shown to occur in germinating winged-bean (Psophocarpus tetragonolobus) seeds, by assaying extracts at pH 8.0 and pH 5.1 with [14C]gelatin as substrate. At pH 8.0, the activity profile of the enzyme shows a steady rise throughout the period of germination, whereas the activity at the acidic pH is very low up to day 5 and then increases sharply reaching a peak o...
