In enzymology, a galactinol-sucrose galactosyltransferase is an enzyme that catalyzes the chemical reaction
alpha-D-galactosyl-(1->3)-1D-myo-inositol + sucrose
\rightleftharpoons
Thus, the two substrates of this enzyme are alpha-D-galactosyl-(1->3)-1D-myo-inositol and sucrose, whereas its two products are myo-inositol and raffinose.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is alpha-D-galactosyl-(1->3)-myo-inositol:sucrose 6-alpha-D-galactosyltransferase. Other names in common use include 1-alpha-D-galactosyl-myo-inositol:sucrose, and 6-alpha-D-galactosyltransferase. This enzyme participates in galactose metabolism.
