The role of stachyose synthase in the oligosaccharide metabolism of legume seeds

Legume seeds contain two major classes of soluble α-galactosides, namely the raffinose family of oligosaccharides and galactosyl cyclitols. They are biosynthetically linked by the enzyme stachyose synthase [galactinol-raffinose galactosyltransferase], which not only forms stachyose from raffinose and galactinol, but also catalyses the galactinol-dependent synthesis of galactosyl cyclitols. Stachyose synthase enzymes Read more…
