An engineered seed protein having a higher percentage of essential amino acids

摘要

This invention pertains to development of seeds and seed storage proteins that are enhanced in the quantity of amino acids that are essential to humans and animals. More specifically, this invention concerns the genetic engineering of the Brazil Nut 2S albumin seed storage protein so that it contains a higher percentage of essential amino acid residues. Expression of a gene encoding this engineered seed storage protein in transgenic plants results in increased accumulation of essential amino acids in the seeds of these plants.
