Sysname
alpha-D-galactosyl-(1->3)-1D-myo-inositol:raffinose galactosyltransferase
Reaction(IUBMB)
alpha-D-galactosyl-(1->3)-1D-myo-inositol + raffinose = myo-inositol + stachyose [RN:R03418 R06042]
Reaction(KEGG)
Substrate
alpha-D-galactosyl-(1->3)-1D-myo-inositol [CPD:C01235];
raffinose [CPD:C00492]
Product
myo-inositol [CPD:C00137];
stachyose [CPD:C01613]
Comment
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.
