Abstract
The effects of myoglobin on exopeptidases of Lactobacillus sake were d etermined. Inhibition of the aminopeptidases increased as the myoglobi n concentration increased; aminopeptidase 3 mas the most affected (90% inhibition). Aminopeptidases 1, 2, and 4 showed similar inhibition le vels (around 60%). Myoglobin did not affect tripeptidase activity. Thu s, myoglobin could limit amino acid generation in meat systems.
