M. Okitsu et al., INHIBITION OF THE ENDOTHELIN-CONVERTING ENZYME BY PEPSIN DIGESTS OF FOOD PROTEINS, Bioscience, biotechnology, and biochemistry, 59(2), 1995, pp. 325-326
Inhibitory activities toward the endothelin-converting enzyme (ECE) we
re detected in pepsin digests of bonito pyrolic appendix and beef, Aft
er Sep-Pak C-18 fractionation, this activity from bonito and beef was
recovered in the 50% and 25% ethanol fractions, respectively, Activiti
es were also recovered in the ultrafiltrate (< 5000 Da), and disappear
ed after a pronase treatment. Therefore, these inhibitory activities m
ay have peptidic properties.
