Objectives A levansucrase from Leuconostoc mesenteroides NTM048 was cloned and expressed and its enzymatic product was characterized. Results The fructansucrase gene from Leuconostoc mesenteroides was cloned and expressed in Escherichia coli. The recombinant enzyme was purified as a single protein and its properties investigated. The polymer produced by the recombinant enzyme was identified as levan...
