Abstract
Disclosed is a new tagatose 6-phosphate 4-epimerase, which is capable of converting fructose 6-phosphate into tagatose 6-phosphate and vice versa. Also disclosed is an application of the enzyme in tagatose production.
Claims2
A method of using a tagatose 6-phosphate 4-epimerase (TiT4E) to catalyze mutual conversion between fructose 6-phosphate and tagatose 6-phosphate, wherein the tagatose 6-phosphate 4-epimerase is selected from the group consisting of:
- (a) a protein having the amino acid sequence set forth in SEQ ID NO:
- 1;
- or
- (b) a protein having an amino acid sequence of ≥90% identity to the amino acid sequence set forth in SEQ ID NO:
- 1, and having an activity of catalyzing mutual conversion between fructose 6-phosphate and tagatose 6-phosphate.
