About 80% of radioactivity was recovered in asymmetrically labeled sucrose from UDP-[¹⁴C]glucose or [¹⁴C]fructose with recombinant mung bean sucrose synthase expressed in Escherichia coli harboring pEB-01. This high recovery is due to the fact that the enzyme conserving the activity of sucrose synthase has a similar affinity for UDP-glucose and fructose to an intact enzyme from the mung bean, but a lower affinity for sucrose.
