Abstract
The present disclosure relates to a composition for producing tagatose, comprising fructose-6-phosphate-4-epimerase, and a method of producing tagatose using the same.
Claims11
A method of producing tagatose, comprising:
- a) producing tagatose-6-phosphate by contacting fructose-6-phosphate with tagatose-bisphosphate aldolase, a microorganism expressing the tagatose-bisphosphate aldolase, or a culture of the microorganism;
- and
- b) producing tagatose by converting tagatose-6-phosphate produced in Step a) into tagatose.
A method of producing tagatose, comprising:
- contacting (a) starch, maltodextrin, sucrose, or a combination thereof with (b) (i) tagatose-6-phosphate phosphatase, (ii) tagatose-bisphosphate aldolase, (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,
- wherein the tagatose-bisphosphate aldolase has activity to convert fructose-6-phosphate into tagatose-6-phosphate.
