Abstract
The present disclosure relates to a fructose-C4-epimerase and a method of preparing tagatose using the same.
Claims8
A vector comprising a polynucleotide encoding a polypeptide which has fructose-C4-epimerase activity and comprising an amino acid sequence of SEQ ID NO:
- 1 or an amino acid sequence having at least 85% identity with SEQ ID NO:
- 1.
A microorganism comprising a polynucleotide encoding a polypeptide which has fructose-C4-epimerase activity and comprising an amino acid sequence of SEQ ID NO:
- 1 or an amino acid sequence having at least 85% identity with SEQ ID NO:
- 1, wherein the microorganism belongs to the genus of Escherichia, the genus of Erwinia, the genus of Serratia, the genus of Providence, the genus of Corynebacteria, or the genus of Brevibacteria.
A method of preparing tagatose comprising converting fructose into tagatose by contacting a composition with the fructose, wherein the composition comprises:
- a polypeptide having fructose-C4-epimerase activity and comprising an amino acid sequence of SEQ ID NO:
- 1 or an amino acid sequence having at least 85% identity with SEQ ID NO:
- 1;
- a microorganism expressing the polypeptide, or cultures of the microorganism.
