Abstract
Provided are a composition for producing tagatose, comprising fructose-6-phosphate 4-epimerase, and a method of producing tagatose using the same.
Claims8
A method of producing tagatose, comprising:
- (a) producing tagatose-6-phosphate by contacting fructose-6-phosphate with tagatose-6-phosphate kinase, a microorganism expressing the tagatose-6-phosphate kinase, or a culture of the microorganism,
- wherein the tagatose-6-phosphate kinase consists of the amino acid sequence of SEQ ID NO:
- 3 or 5;
- and
- (b) producing tagatose by contacting the produced tagatose-6-phosphate with tagatose-6-phosphatase, a microorganism expressing the tagatose-6-phosphate phosphatase, or a culture of the microorganism.
2 more elements
A method of producing tagatose, comprising contacting (a) starch, maltodextrin, sucrose, or a combination thereof;
- with (b) (i) tagatose-6-phosphate phosphatase, (ii) tagatose-6-phosphate kinase consists of the amino acid sequence of SEQ ID NO:
- 3 or 5, (iii) glucose-6-phosphate-isomerase, (iv) phosphoglucomutase or glucokinase, (v) phosphorylase, and (vi) one or more of α-amylase, pullulanase, isoamylase, glucoamylase, or sucrase;
- and (c) phosphate.
