| Sysname |
alpha-D-galactosyl-(1->3)-1D-myo-inositol:sucrose
6-alpha-D-galactosyltransferase |
|---|
| Reaction(IUBMB) |
alpha-D-galactosyl-(1->3)-1D-myo-inositol + sucrose = myo-inositol +
raffinose [RN:R02411 R06071] |

| Reaction(KEGG) |
R02411 R06071(G)
 |
|---|
| Substrate |
alpha-D-galactosyl-(1->3)-1D-myo-inositol [CPD:C01235];
sucrose [CPD:C00089] |
|---|
| Product |
myo-inositol [CPD:C00137];
raffinose [CPD:C00492] |
|---|
| Comment |
4-Nitrophenyl alpha-D-galactopyranoside can also act as donor. The
enzyme also catalyses an exchange reaction between raffinose and
sucrose (cf. EC 2.4.1.123, inositol 3-alpha-galactosyltransferase). |
