ID 2.4.1.82 DE galactinol--sucrose galactosyltransferase. AN 1-alpha-D-galactosyl-myo-inositol:sucrose 6-alpha-D- AN galactosyltransferase. AN raffinose synthase. CA alpha-D-galactosyl-(1->3)-1D-myo-inositol + sucrose = myo-inositol + CA raffinose. CC -!- 4-Nitrophenyl-alpha-D-galactopyranoside can also act as donor. CC -!- Also catalyzes an exchange reaction between raffinose and sucrose CC (cf. EC 2.4.1.123).
