Abstract

Three peptides that inhibited angiotensin I converting enzyme (ACE) were isolated from a peptic hydrolyzate of heated sardine muscle. The preparation involved SP-Sephadex C-25 and Toyopearl HW-40 chromatography followed by three steps of high-performance liquid chromatography. The amino acid sequences of these peptides, identified by Edman degradation, were: B-1, Val-Lys-Ala-Gly-Phe; B-2, Lys-Val-Leu-Ala-Gly-Met; and B-3, Leu-Lys-Leu. The IC50 values of these peptides for ACE from rabbit lung were 83, 30, and 188 μM, respectively. These peptides were synthesized by the solid-phase method, and the IC50 values of the synthetic peptides were similar to those of B-1, B-2, and B-3. These results indicated that all amino acids in B-1, B-2, and B-3 may be in the L-configuration. Fourteen kinds of actins derived from humans, rabbits, rats, mice, soy beans, maize, and so on contained the B-1 sequence of five amino acids.
