Abstract
|
|
|
A study on the active center of the acid protease from Penicillium sp. was conducted, and also the milk clotting activity of acid prorease was measured.
1. PCMB failed to influence the proteolytic activity of acid protease, indicating that a reactive sulfhydryl group is not required for the enzymatic activity.
2. e-amino caproic acid did not show any inhibitory effect on the proteolytic activity of acid protease.
3. Also 2, 4-dinitro phenol did not show any inhibitory effect on the enzyme activity.
4. Acid protease from Penicillium sp. showed a strong milk clotting activity in the presence of Ca ion.
5. This enzyme had a strong proteolytic activity on various substrate, such as casein, denatured hemoglobin, ovalbumin, denatured bovine muscle protein, denatured percine muscle protein and denatured chicken muscle protein.
