Hexosyltransferases
BRITE hierarchy
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)
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).
History
