Abstract

Novokinin (RPLKPW), LPYPR, and rubiscolin (YPLDLF) are bioactive peptides with respective hypotensive, hypocholesterolemic, and memory-enhancing activities. We generated transgenic soybean lines that expressed modified forms of the α′ subunit of seed storage protein β-conglycinin containing tandem repeats of these bioactive peptides. The modified α′ subunits constituted up to 0.2% of extracted proteins from the transgenic seeds.
