alpha-D-galactosyl-(1->3)-1D-myo-inositol:raffinose galactosyltransferase

This enzyme also catalyses galactosyl transfer from stachyose to raffinose (shown by labelling) [4]. For synthesis of the substrate, see EC 2.4.1.123, inositol 3-alpha-galactosyltransferase. See also EC 2.4.1.82, galactinol---sucrose galactosyltransferase.
