Seed storage albumins: biosynthesis, trafficking and structures

Abstract

Seed storage albumins are water-soluble and highly abundant proteins that are broken-down during seed germination to provide nitrogen and sulfur for the developing seedling. During seed maturation these proteins are subject to post-translational modifications and trafficking before they are deposited in great quantity and with great stability in dedicated vacuoles. This review will cover the subcellular movement, biochemical processing and mature structures of seed storage napins.
