In enzymology, a galactinol-raffinose galactosyltransferase (EC 2.4.1.67) is an enzyme that catalyzes the chemical reaction
alpha-D-galactosyl-(1→3)-1D-myo-inositol + raffinose
Thus, the two substrates of this enzyme are α-D-galactosyl-(1→3)-1D-myo-inositol and raffinose, whereas its two products are myo-inositol and stachyose.
This enzyme participates in galactose metabolism.
Nomenclature
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:raffinose galactosyltransferase. Other names in common use include galactinol-raffinose galactosyltransferase, and stachyose synthetase.
