抄録

Peptides showing inhibitory activity against the angiotensin I-converting enzyme (ACE) were investigated from the fibroin fraction of discarded silk fabric. Fibroin, which was hydrolyzed with alcalase after partial hydrolysis with hot aqueous 40% CaCl₂, released two major active peptides showing ACE-inhibitory activity. The two peptides were identified as glycyl-valyl-glycyl-tyrosine (GVGY) and glycyl-valyl-glycyl-alanyl-glycyl-tyrosine (GVGAGY) by analyses with a protein sequencer and LC/MS/MS. GVGY, whose ACE-inhibitory activity has not previously been reported, showed a blood pressure-depressing effect on spontaneously hypertensive rat (SHR).
