Novokinin (Arg-Pro-Leu-Lys-Pro-Trp), which has been designed based on the structure of ovokinin (2–7), significantly reduces the systolic blood pressure at a dose of 100 μg/kg after oral administration in spontaneously hypertensive rats (SHRs). In this study, we generated a transgenic soybean which accumulates novokinin. A vector encoding a modified β-conglycinin α′ subunit (4novokinin-α′) in which four novokinin sequences have been incorporated by site-directed mutagenesis was introduced into somatic embryos by whisker-mediated gene transformation to produce a transgenic soybean. The 4novokinin-α′ occupied 0.5% of total soluble protein and 5% of the β-conglycinin α′ subunit in the transgenic soybean seeds. Protein extracted from the transgenic soybean reduced systolic blood pressure after single oral administration in SHRs at a dose of 0.15 g/kg. Defatted flour from the transgenic soybean also reduced the systolic blood pressure at a dose of 0.25 g/kg. Thus, the 4novokinin-α′ produced in soybean exhibited an anti-hypertensive activity in SHRs after oral administration.
