Abstract

The effects of myoglobin on exopeptidases of Lactobacillus sake were determined. Inhibition of the aminopeptidases increased as the myoglobin concentration increased; aminopeptidase 3 was the most affected (90% inhibition). Aminopeptidases 1, 2, and 4 showed similar inhibition levels (around 60%). Myoglobin did not affect tripeptidase activity. Thus, myoglobin could limit amino acid generation in meat systems.

摘要

测定了肌红蛋白对清酒乳杆菌外肽酶的影响。随着肌红蛋白浓度的增加，氨肽酶的抑制作用增强；氨肽酶3受影响最大（抑制率达90%）。氨肽酶1、2和4表现出相似的抑制水平（约60%）。肌红蛋白不影响三肽酶活性。因此，肌红蛋白可能会限制肉类系统中氨基酸的生成。
