Other claims from this paper (6)
- Observation N-CBZ-L-Tyr-pNP hydrolase activity per cotyledon increased after germination, reaching its maximum after 6 days.
- Observation BTEE hydrolase activity per cotyledon increased after germination, reaching its maximum after 10 days.
- Observation Acid phosphatase activity per cotyledon increased after germination, reaching its maximum after 10 days.
- Observation Aminopeptidase AP1 activity reached its maximum after 2 days and then declined immediately after germination.
- Observation α-N-benzoyl-D,L-arginine-p-nitroanilide hydrolase activity was maintained at a maximum between days 2 and 10 and then declined.
- Mechanism Differences in the timing and magnitude of N-CBZ-L-Tyr-pNP and BTEE hydrolase activities suggest that at least two enzymes contribute to these activities.
