Abstract:
Inhibitory activities toward the endothelin-converting enzyme (ECE) were detected in pepsin digests of bonito pyrolic appendix and beef. After Sep-Pak C18 fractionation, this activity from bonito and beef was recovered in the 50% and 25% ethanol fractions, respectively. Activities were also recovered in the ultrafiltrate (< 5000 Da), and disappeared after a pronase treatment. Therefore, these inhibitory activities may have peptidic properties.
