BRITE hierarchy
Sysname
raffinose:raffinose alpha-D-galactosyltransferase
Reaction(IUBMB)
2 raffinose = 1F-alpha-D-galactosylraffinose + sucrose [RN:R00039 R06139]
Reaction(KEGG)
R00039 R06139(G);
(other) R08616
Show
Substrate
raffinose [CPD:C00492]
Product
1F-alpha-D-galactosylraffinose [CPD:C08242];
sucrose [CPD:C00089]
Comment
The 3F position of raffinose can also act as galactosyl acceptor; the enzyme is involved in the accumulation of the tetrasaccharides lychnose and isolychnose in the leaves of Cerastium arvense and other plants of the family Caryophyllaceae during late autumn.
