[Changes in activity of proteolytic enzymes (BAPAases) in germinating buckwheat and rye seeds].

The interrelationship between the activity of proteolytic enzymes (BAPAases) from buckwheat and rye seeds hydrolyzing Nalpha-benzoyl-DL-arginine-p-nitroanilide (BAPA) and the amount of the antiserum to these enzymes necessary to obtain a certain inhibition level has been studied at different stages of seed germination. The data obtained show that the increase of the BAPAase activity in germinating rye seeds is due to de novo synthesis of this enzyme. During this process antigenically identical enzyme molecules are synthesized in roots and shoots of the developing plant.
