Accepted name: |
raffinose—raffinose α-galactosyltransferase |
Reaction: |
2 raffinose = 1F-α-D-galactosylraffinose + sucrose |
Glossary: |
raffinose = β-D-fructofuranosyl α-D-galactopyranosyl-(1→6)-α-D-glucopyranoside |
Other name(s): |
raffinose (raffinose donor) galactosyltransferase; raffinose:raffinose α-galactosyltransferase; raffinose—raffinose α-galactotransferase |
Systematic name: |
raffinose:raffinose α-D-galactosyltransferase |
Comments: |
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. |
