. "The enzyme from Synechocystis sp. strain PCC 6803 is not specific for UDP-glucose as it can use ADP-glucose and, to a lesser extent, GDP-glucose as substrates." . "The enzyme from rice leaves is activated by glucose 6-phosphate but that from cyanobacterial species is not." . "While the reaction catalyzed by this enzyme is reversible, the enzyme usually works in concert with EC 3.1.3.24 to form sucrose, making the above reaction essentially irreversible." . "The F in sucrose 6(F)-phosphate is used to indicate that the fructose residue of sucrose carries the substituent." . . . "Sucrose-phosphate synthase" . "UDP-glucose-fructose-phosphate glucosyltransferase" . "Sucrosephosphate--UDP glucosyltransferase" . "UDP-glucose + D-fructose 6-phosphate = UDP + sucrose 6(F)-phosphate." . "Manganese or magnesium" .
