Abstract

The invention is directed to novel enzymes that convert sucrose to isomaltulose. More particularly, the present invention discloses novel sucrose isomerases, polynucleotides encoding these sucrose isomerases, methods for isolating such polynucleotides and nucleic acid constructs that express these polynucleotides. Also disclosed are cells, including transformed bacterial or plant cells, and differentiated plants comprising cells, which contain these sucrose isomerase-encoding polynucleotides, as well as extracts thereof. Methods of producing isomaltulose are also disclosed which use the polypeptides, polynucleotides, cells, cell extracts and plants of the invention.
