Abstract

A fructosyltransferase from Leuconostoc mesenteroides TL1 was purified. The molecular mass of the enzyme was estimated to be 38 kDa based on the activity staining. The pH and temperature optima of the enzyme were 6.3 and $40^{\circ}C$, respectivly. Structural analysis of the polymer prepared from sucrose by the enzyme was determined by NMR Spectroscopy: It shows the heterogeneous linkages of levan-like fructan and dextran-like glucan.
