ENZYME: 2.4.1.67

Entry

EC 2.4.1.67                 Enzyme

Name

galactinol---raffinose galactosyltransferase;
galactinol-raffinose galactosyltransferase;
stachyose synthetase;
alpha-D-galactosyl-(1->3)-myo-inositol:raffinose galactosyltransferase

Class

Transferases;
Glycosyltransferases;
Hexosyltransferases

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)

R03418 R06042(G)

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.
