General Information

EC Number General Information Comment Organism
2.4.1.82 physiological function raffinose synthase catalyzes the transfer of galactosyl residue from galactinol to sucrose to form raffinose Oryza sativa
2.4.1.123 physiological function galactinol synthase catalyzes the first committed step in the biosynthesis of raffinose family oligosaccharides and plays a key regulatory role in the carbon partitioning between sucrose and raffinose family oligosaccharides Oryza sativa
