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.

The current disclosure provides a process for enzymatically converting a saccharide into tagatose. The invention also relates to a process for preparing tagatose where the process involves converting fructose 6-phosphate (F6P) to tagatose 6-phosphate (T6P), catalyzed by an epimerase, and converting the T6P to tagatose, catalyzed by a phosphatase.

The present disclosure relates to tagatose-6-phosphate phosphatase consisting of an amino acid sequence of SEQ ID NO: 1, a nucleic acid encoding the tagatose-6-phosphate phosphatase, and a transformant comprising the nucleic acid. Additionally, the present disclosure relates to a composition for producing tagatose, which comprises the tagatose-6-phosphate phosphatase of the present disclosure, and a method for producing tagatose using the tagatose-6-phosphate phosphatase of the present disclosure.
