ENZYME: 2.4.1.166

Entry

EC 2.4.1.166                Enzyme

Name

raffinose---raffinose alpha-galactosyltransferase;
raffinose (raffinose donor) galactosyltransferase;
raffinose:raffinose alpha-galactosyltransferase;
raffinose---raffinose alpha-galactotransferase

Class

Transferases;
Glycosyltransferases;
Hexosyltransferases

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

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.
